Thorlabs' Quantalux® Scientific CMOS (sCMOS) Cameras offer high sensitivity with high dynamic range, enabling the detection of dim features without overexposing bright details. The combination of extremely low read noise (<1 e- median) and high quantum efficiency peaking at 61% at 600 nm provides excellent performance in even the most demanding low light applications, such as fluorescence microscopy.

Compact Package or Hermetically Sealed TE-Cooled Camera
Our Quantalux sCMOS cameras are offered in two styles: a passively cooled compact package (Item # CS2100M-USB) and a hermetically sealed package with a thermoelectric cooler (TEC) that cools the sensor (Item # CC215MU). Both use a fan-free design to reduce dark current without adding image blur from vibrations. The CC215MU camera's active TE-cooling provides greater dark current reduction when compared to the passively cooled camera; however, the total dark current is also a function of exposure time. For high light levels requiring short exposure times (less than 500 ms), the passively cooled camera is generally sufficient. We strongly recommend a cooled camera for applications with low light levels requiring exposures longer than 500 ms. Please see the Camera Noise tab for more details on the various sources of camera noise and how it impacts the choice between a standard and cooled camera.

Removable Protective Window
All Quantalux cameras are configured with a clear, broadband, AR-coated protective window to preserve the sCMOS sensor spectral response from 400 - 700 nm. The C-mount adapter and other front end components are removable to provide access to the protective window. If the image spectrum must be limited, for example to eliminate unwanted near-infrared light, we offer a wide range of high-quality interference and colored glass optical filters that can easily be user-installed in both cameras.

Software and Triggering
Each camera features a USB 3.0 interface for compatibility with most computers, and can be controlled with our ThorCam software for use with Windows 7 and 10 operating systems. Developers can leverage our fully featured API and SDK; please see the Software tab for more information.

Our cameras have triggering options that enable custom timing and system control; for more details, please see the Triggering tab. External triggering requires a connection to the auxiliary port of the camera. Accessory cables and boards to "break out" the individual signals are available below. Please note that the USB3-MBA-118 USB 3.0 cable is only suitable for the CS2100M-USB compact camera; the CC215MU cooled camera ships with an appropriate USB 3.0 cable.

ThorCam™

ThorCam is a powerful image acquisition software package that is designed for use with our cameras on 32- and 64-bit Windows® 7 or 10 systems. This intuitive, easy-to-use graphical interface provides camera control as well as the ability to acquire and play back images. Single image capture and image sequences are supported. Please refer to the screenshots below for an overview of the software's basic functionality.

Application programming interfaces (APIs) and a software development kit (SDK) are included for the development of custom applications by OEMs and developers. The SDK provides easy integration with a wide variety of programming languages, such as C, C++, C#, Python, and Visual Basic .NET. Support for third-party software packages, such as LabVIEW, MATLAB, and µManager* is available. We also offer example Arduino code for integration with our TSI-IOBOB2 Interconnect Break-Out Board.

*µManager control of Zelux and 1.3 MP Kiralux cameras is not currently supported. When controlling the Kiralux Polarization-Sensitive Camera using µManager, only intensity images can be taken; the ThorCam software is required to produce images with polarization information.

Thorcam GUI Window

Camera Control and Image Acquisition

Camera Control and Image Acquisition functions are carried out through the icons along the top of the window, highlighted in orange in the image above. Camera parameters may be set in the popup window that appears upon clicking on the Tools icon. The Snapshot button allows a single image to be acquired using the current camera settings.

The Start and Stop capture buttons begin image capture according to the camera settings, including triggered imaging.

Timed Series and Review of Image Series

The Timed Series control, shown in Figure 1, allows time-lapse images to be recorded. Simply set the total number of images and the time delay in between captures. The output will be saved in a multi-page TIFF file in order to preserve the high-precision, unaltered image data. Controls within ThorCam allow the user to play the sequence of images or step through them frame by frame.

Measurement and Annotation

As shown in the yellow highlighted regions in the image above, ThorCam has a number of built-in annotation and measurement functions to help analyze images after they have been acquired. Lines, rectangles, circles, and freehand shapes can be drawn on the image. Text can be entered to annotate marked locations. A measurement mode allows the user to determine the distance between points of interest.

The features in the red, green, and blue highlighted regions of the image above can be used to display information about both live and captured images.

ThorCam also features a tally counter that allows the user to mark points of interest in the image and tally the number of points marked (see Figure 2). A crosshair target that is locked to the center of the image can be enabled to provide a point of reference.

Third-Party Applications and Support

ThorCam is bundled with support for third-party software packages such as LabVIEW, MATLAB, and .NET. Both 32- and 64-bit versions of LabVIEW and MATLAB are supported. A full-featured and well-documented API, included with our cameras, makes it convenient to develop fully customized applications in an efficient manner, while also providing the ability to migrate through our product line without having to rewrite an application.

Performance Considerations

Please note that system performance limitations can lead to "dropped frames" when image sequences are saved to the disk. The ability of the host system to keep up with the camera's output data stream is dependent on multiple aspects of the host system. Note that the use of a USB hub may impact performance. A dedicated connection to the PC is preferred. USB 2.0 connections are not supported.

First, it is important to distinguish between the frame rate of the camera and the ability of the host computer to keep up with the task of displaying images or streaming to the disk without dropping frames. The frame rate of the camera is a function of exposure and readout (e.g. clock, ROI) parameters. Based on the acquisition parameters chosen by the user, the camera timing emulates a digital counter that will generate a certain number of frames per second. When displaying images, this data is handled by the graphics system of the computer; when saving images and movies, this data is streamed to disk. If the hard drive is not fast enough, this will result in dropped frames.

One solution to this problem is to ensure that a solid state drive (SSD) is used. This usually resolves the issue if the other specifications of the PC are sufficient. Note that the write speed of the SSD must be sufficient to handle the data throughput.

Larger format images at higher frame rates sometimes require additional speed. In these cases users can consider implementing a RAID0 configuration using multiple SSDs or setting up a RAM drive. While the latter option limits the storage space to the RAM on the PC, this is the fastest option available. ImDisk is one example of a free RAM disk software package. It is important to note that RAM drives use volatile memory. Hence it is critical to ensure that the data is moved from the RAM drive to a physical hard drive before restarting or shutting down the computer to avoid data loss.

Triggered Camera Operation

Our scientific cameras have three externally triggered operating modes: streaming overlapped exposure, asynchronous triggered acquisition, and bulb exposure driven by an externally generated trigger pulse. The trigger modes operate independently of the readout (e.g., binning) settings as well as gain and offset. Figures 1 through 3 show the timing diagrams for these trigger modes, assuming an active low external TTL trigger.

Camera Timing Diagram

Figure 1: Streaming overlapped exposure mode. When the external trigger goes low, the exposure begins, and continues for the software-selected exposure time, followed by the readout. This sequence then repeats at the set time interval. Subsequent external triggers are ignored until the camera operation is halted. For the definition of the TTL signals, please see the Pin Diagrams tab.

Figure 2: Asynchronous triggered acquisition mode. When the external trigger signal goes low, an exposure begins for the preset time, and then the exposure is read out of the camera. During the readout time, the external trigger is ignored. Once a single readout is complete, the camera will begin the next exposure only when the external trigger signal goes low.

Figure 4: 
The ThorCam Camera Settings window. The red and blue highlighted regions indicate the trigger settings as described in the text.

External triggering enables these cameras to be easily integrated into systems that require the camera to be synchronized to external events. The Strobe Output goes high to indicate exposure; the strobe signal may be used in designing a system to synchronize external devices to the camera exposure. External triggering requires a connection to the auxiliary port of the camera. We offer the 8050-CAB1 auxiliary cable as an optional accessory. Two options are provided to "break out" individual signals. The TSI-IOBOB provides SMA connectors for each individual signal. Alternately, the TSI-IOBOB2 also provides the SMA connectors with the added functionality of a shield for Arduino boards that allows control of other peripheral equipment. More details on these three optional accessories are provided below.

Trigger settings are adjusted using the ThorCam software. Figure 4 shows the Camera Settings window, with the trigger settings highlighted with red and blue squares. Settings can be adjusted as follows:

  • "Hardware Trigger" (Red Highlight) Set to "None": The camera will simply acquire the number of frames in the "Frames per Trigger" box when the capture button is pressed in ThorCam.
  • "Hardware Trigger" Set to "Standard": There are Two Possible Scenarios:
    • "Frames per Trigger" (Blue Highlight) Set to Zero or >1: The camera will operate in streaming overlapped exposure mode (Figure 1).
    • "Frames per Trigger" Set to 1: Then the camera will operate in asynchronous triggered acquisition mode (Figure 2).
  • "Hardware Trigger" Set to "Bulb (PDX) Mode": The camera will operate in bulb exposure mode, also known as Pulse Driven Exposure (PDX) mode (Figure 3).

In addition, the polarity of the trigger can be set to "On High" (exposure begins on the rising edge) or "On Low" (exposure begins on the falling edge) in the "Hardware Trigger Polarity" box (highlighted in red in Figure 4).

Equal Exposure Pulse (EEP) Mode

The Equal Exposure Pulse (EEP) is an output signal available on the Quantalux camera's I/O connector. When selected in the ThorCam settings dialog, the STROBE_OUT signal is reconfigured to be active only after the CMOS sensor's rolling reset function has completed. The signal will remain active until the sensor's rolling readout function begins. This means that the signal is active only during the time when all of the sensor's pixels have been reset and are actively integrating. The resulting image will not show an exposure gradient typical of rolling reset sensors. Figure 5 shows an example of a strobe-driven exposure, where STROBE_OUT is used to trigger an external light source; the resulting image shows a gradient as not all sensor rows are integrating charge for the same length of time when the light source is on. Figure 6 shows an example of an EEP exposure: the exposure time is lengthened, and the trigger output signal shifted to the time when all rows are integrating charge, yielding an image with equal illumination across the frame.

Please note that EEP will have no effect on images that are constantly illuminated. There are several conditions that must be met to use EEP mode; these are detailed in the User Guide.

Camera Triggering with TSI-IOBOB2 Shield for Arduino
Figure 5: A schematic showing a system using the TSI-IOBOB2 to facilitate system integration and control.
While the diagram shows the back panel of our Quantalux™ sCMOS Camera, our Scientific CCD cameras can be used as well.

As an example of how camera triggering can be integrated into system control is shown in Figure 5. In the schematic, the camera is connected to the TSI-IOBOB2 break-out board / shield for Arduino using a 8050-CAB1 cable. The pins on the shield can be used to deliver signals to simultaneously control other peripheral devices, such as light sources, shutters, or motion control devices. Once the control program is written to the Arduino board, the USB connection to the host PC can be removed, allowing for a stand-alone system control platform; alternately, the USB connection can be left in place to allow for two-way communication between the Arduino and the PC. Configuring the external trigger mode is done using ThorCam as described above.

Camera Noise and Temperature

Overview
When purchasing a camera, an important consideration is whether or not the application will require a cooled sensor. Generally, most applications have high signal levels and do not require cooling. However, for certain situations, generally under low light levels where long exposures are necessary, cooling will provide a benefit. In the tutorial below, we derive the following "rule of thumb": for exposures less than 1 second, a standard camera is generally sufficient; for exposures greater than 1 second, cooling could be beneficial; for exposures greater than 5 seconds, cooling is generally recommended; and for exposures above 10 seconds, cooling is usually required. If you have questions about which domain your application will fall, you might consider estimating the signal levels and noise sources by following the steps detailed in the tutorial below, where we present sample calculations using the specifications for our 1.4 megapixel cameras. Alternatively you can contact us, and one of our scientific camera specialists will help you decide which camera is right for you.

Sources of Noise

Noise in a camera image is the aggregate spatial and temporal variation in the measured signal, assuming constant, uniform illumination. There are several components of noise:

  • Dark Shot Noise (σD): Dark current is a current that flows even when no photons are incident on the camera. It is a thermal phenomenon resulting from electrons spontaneously generated within the silicon chip (valence electrons are thermally excited into the conduction band). The variation in the amount of dark electrons collected during the exposure is the dark shot noise. It is independent of the signal level but is dependent on the temperature of the sensor as shown in Table 1.
  • Read Noise (σR): This is the noise generated in producing the electronic signal. This results from the sensor design but can also be impacted by the design of the camera electronics. It is independent of signal level and temperature of the sensor, and is larger for faster CCD pixel clock rates.
  • Photon Shot Noise (σS): This is the statistical noise associated with the arrival of photons at the pixel. Since photon measurement obeys Poisson statistics, the photon shot noise is dependent on the signal level measured. It is independent of sensor temperature.
  • Fixed Pattern Noise (σF): This is caused by spatial non-uniformities of the pixels and is independent of signal level and temperature of the sensor. Note that fixed pattern noise will be ignored in the discussion below; this is a valid assumption for the CCD cameras sold here but may need to be included for other non-scientific-grade sensors.

Total Effective Noise

The total effective noise per pixel is the quadrature sum of each of the noise sources listed above:

(1)

Total noise equation 1

Here, σD is the dark shot noise, σR is the read noise (for sample calculations, we will use our 1.4 megapixel cameras, which use the ICX285AL sensor. Typically the read noise is less than 10 e- for scientific-grade cameras using the ICX285AL CCD; we will assume a value of 10 e- in this tutorial), and σS is the photon shot noise. If σS>>σD and σS>>σR, then σeff is approximately given by the following:

(2)

Total noise equation 1

Again, fixed pattern noise is ignored, which is a good approximation for scientific-grade CCDs but may need to be considered for non-scientific-grade sensors.

Temperature Dark Current (ID)
-20 °C 0.1 e-/(s•pixel)
0 °C 1 e-/(s•pixel)
25 °C 5 e-/(s•pixel)

Dark Shot Noise as a function of exposure

Figure 1: Plot of dark shot noise and read noise as a function of exposure for three sensor temperatures for a sample camera. This plot uses logarithmic scales for both axes.The dotted vertical line at 5 s indicates the values calculated as the example in the text.

Dark Shot Noise and Sensor Temperature

As mentioned above, the dark current is a thermal effect and can therefore be reduced by cooling the sensor. Table 1 lists typical dark current values for a sample camera with a CCD sensor. As the dark current results from spontaneously generated electrons, the dark current is measured by simply "counting" these electrons. Since counting electrons obeys Poisson statistics, the noise associated with the dark current ID is proportional to the square root of the number of dark electrons that accumulate during the exposure. For a given exposure, the dark shot noise, σD, is therefore the square root of the ID value from Table 1 (for a given sensor temperature) multiplied by the exposure time t in seconds:

(3)

Dark noise equation 1

Since the dark current decreases with decreasing temperature, the associated noise can be decreased by cooling the camera. For example, assuming an exposure of 5 seconds, the dark shot noise levels for the three sensor temperatures listed in the table are

(4)

Example 1 equation 3
Example 1 equation 3
Example 1 equation 3

Figure 1, which is a plot of the dark shot noise as a function of exposure for the three temperatures listed in Table 1, illustrates how the dark shot noise increases with increasing exposure. Figure 1 also includes a plot of the upper limit of the read noise.

If the photon shot noise is significantly larger than the dark shot noise, then cooling provides a negligible benefit in terms of the noise, and our standard package cameras will work well.

Photon Shot Noise

If S is the number of "signal" electrons generated when a photon flux of N photons/second is incident on each pixel of a sensor with a quantum efficiency QE and an exposure duration of t seconds, then

Shot noise equation 2

From S, the photon shot noise, σS, is given by:

If we assume that there is a sufficiently high photon flux and quantum efficiency to allow for a signal S of 10,000 e- to accumulate in a pixel with an exposure of 5 seconds, then the estimated shot noise, σS, would be the square root of 10,000, or 100 e-. The read noise is 10 e- (independent of exposure time). For an exposure of 5 seconds and sensor temperatures of 25, 0, and -25 °C, the dark shot noise is given in equation (4). The effective noise is:

The signal-to-noise ratio (SNR) is a useful figure of merit for image quality and is estimated as:

From Equation 7, the SNR values for the three sensor temperatures are:

Total noise equation 1

As the example shows, there is a negligible benefit to using a cooled camera compared to a non-cooled camera operating at room temperature, and the photon shot noise is the dominant noise source in this example. In this case our standard package cameras should therefore work quite well.

However, if the light levels were lower such that a 100 second exposure was required to achieve 900 e- per pixel, then the shot noise would be 30 e-. The estimated dark shot noise would be 22.4 e- at 25 °C, while at -20 °C the dark shot noise would be 3.2 e-. The total effective noise would be

Exposure Camera Recommendation
<1 s Standard Non-Cooled Camera Generally Sufficient
1 s to 5 s Cooled Camera Could Be Helpful
5 s to 10 s Cooled Camera Recommended
>10 s Cooled Camera Usually Required

Table 2: From the results shown in Figure 1, these are the general "rule of thumb" recommendations related to colling considerations based on the exposure requirements of an application. Please keep in mind that some applications are more sensitive to noise than others.

In this example, the dark shot noise is a more significant contributor to the total noise for the 25 °C sensor than for the -25 °C sensor. Depending on the application's noise budget, a cooled camera may be beneficial.

Figure 2 shows plots of the different noise components, including dark shot noise at three sensor temperatures, as a function of exposure time for three photon fluxes. The plots show that dark shot noise is not a significant contributor to total noise except for low signal (and consequently long exposure) situations. While the photon flux levels used for the calculations are given in the figure, it is not necessary to know the exact photon flux level for your application. Figure 2 suggests a general metric based on exposure time that can be used to determine whether a cooled camera is required if the exposure time can be estimated, and these results are summarized in Table 2. If you find that your dominant source of noise is due to the read noise, then we recommend running the camera at a lower CCD pixel clock rate of 20 MHz, since that will offer a lower read noise.

Figure 2: Noise from all sources as a function of exposure for three different photon fluxes: (a) low, (b) medium, and (c) high. In (c) the signal and photon shot noise saturate above approximately 20 seconds because the pixel becomes saturated at the corresponding incident photon levels. A quantum efficiency of 60% was used for the calculations. Note that these plots use logarithmic scales for both axes.

Other Considerations

Thermoelectric cooling should also be considered for long exposures even where the dark shot noise is not a significant contributor to total noise because cooling also helps to reduce the effects of hot pixels. Hot pixels cause a "star field" pattern that appears under long exposures. Figure 3 shows an example of this star field pattern for images taken using cameras with and without TEC cooling with an exposure of 10 seconds.

Can C-mount and CS-mount cameras and lenses be used with each other?

Characteristics of C-mount lens mounts.
Click to Enlarge

Figure 1: C-mount lenses and cameras have the same flange focal distance (FFD), 17.526 mm. This ensures light through the lens focuses on the camera's sensor. Both components have 1.000"-32 threads, sometimes referred to as "C-mount threads".
Characteristics of CS-mount lens mounts.
Click to Enlarge

Figure 2: CS-mount lenses and cameras have the same flange focal distance (FFD), 12.526 mm. This ensures light through the lens focuses on the camera's sensor. Their 1.000"-32 threads are identical to threads on C-mount components, sometimes referred to as "C-mount threads."

The C-mount and CS-mount camera system standards both include 1.000"-32 threads, but the two mount types have different flange focal distances (FFD, also known as flange focal depth, flange focal length, register, flange back distance, and flange-to-film distance). The FFD is 17.526 mm for the C-mount and 12.526 mm for the CS-mount (Figures 1 and 2, respectively).

Since their flange focal distances are different, the C-mount and CS-mount components are not directly interchangeable. However, with an adapter, it is possible to use a C-mount lens with a CS-mount camera.

Mixing and Matching
C-mount and CS-mount components have identical threads, but lenses and cameras of different mount types should not be directly attached to one another. If this is done, the lens' focal plane will not coincide with the camera's sensor plane due to the difference in FFD, and the image will be blurry.

With an adapter, a C-mount lens can be used with a CS-mount camera (Figures 3 and 4). The adapter increases the separation between the lens and the camera's sensor by 5.0 mm, to ensure the lens' focal plane aligns with the camera's sensor plane.

In contrast, the shorter FFD of CS-mount lenses makes them incompatible for use with C-mount cameras (Figure 5). The lens and camera housings prevent the lens from mounting close enough to the camera sensor to provide an in-focus image, and no adapter can bring the lens closer.

It is critical to check the lens and camera parameters to determine whether the components are compatible, an adapter is required, or the components cannot be made compatible.

1.000"-32 Threads
Imperial threads are properly described by their diameter and the number of threads per inch (TPI). In the case of both these mounts, the thread diameter is 1.000" and the TPI is 32. Due to the prevalence of C-mount devices, the 1.000"-32 thread is sometimes referred to as a "C-mount thread." Using this term can cause confusion, since CS-mount devices have the same threads.

Measuring Flange Focal Distance
Measurements of flange focal distance are given for both lenses and cameras. In the case of lenses, the FFD is measured from the lens' flange surface (Figures 1 and 2) to its focal plane. The flange surface follows the lens' planar back face and intersects the base of the external 1.000"-32 threads. In cameras, the FFD is measured from the camera's front face to the sensor plane. When the lens is mounted on the camera without an adapter, the flange surfaces on the camera front face and lens back face are brought into contact.

A CS-Mount lens is not compatible with a C-Mount camera.
Click to Enlarge

Figure 5: A CS-mount lens is not directly compatible with a C-mount camera, since the light focuses before the camera's sensor. Adapters are not useful, since the solution would require shrinking the flange focal distance of the camera (blue arrow).

Figure 4: An adapter with the proper thickness moves the C-mount lens away from the CS-mount camera's sensor by an optimal amount, which is indicated by the length of the purple arrow. This allows the lens to focus light on the camera's sensor, despite the difference in FFD.

Do Thorlabs' scientific cameras need an adapter?

A C-mount lens can be mounted on a Zelux camera, when the correct adapter is used.
Click to Enlarge

Figure 6: An adapter can be used to optimally position a C-mount lens on a camera whose flange focal distance is less than 17.526 mm. This sketch is based on a Zelux camera and its SM1A10Z adapter.

Figure 7: An adapter can be used to optimally position a CS-mount lens on a camera whose flange focal distance is less than 12.526 mm. This sketch is based on a Zelux camera and its SM1A10 adapter.

All Kiralux™ and Quantalux® scientific cameras are factory set to accept C-mount lenses. When the attached C-mount adapters are removed from the passively cooled cameras, the SM1 (1.035"-40) internal threads in their flanges can be used. The Zelux scientific cameras also have SM1 internal threads in their mounting flanges, as well as the option to use a C-mount or CS-mount adapter.

The SM1 threads integrated into the camera housings are intended to facilitate the use of lens assemblies created from Thorlabs components. Adapters can also be used to convert from the camera's C-mount configurations. When designing an application-specific lens assembly or considering the use of an adapter not specifically designed for the camera, it is important to ensure that the flange focal distances (FFD) of the camera and lens match, as well as that the camera's sensor size accommodates the desired field of view (FOV).

Made for Each Other: Cameras and Their Adapters
Fixed adapters are available to configure the Zelux cameras to meet C-mount and CS-mount standards (Figures 6 and 7). These adapters, as well as the adjustable C-mount adapters attached to the passively cooled Kiralux and Quantalux cameras, were designed specifically for use with their respective cameras.

While any adapter converting from SM1 to 1.000"-32 threads makes it possible to attach a C-mount or CS-mount lens to one of these cameras, not every thread adapter aligns the lens' focal plane with a specific camera's sensor plane. In some cases, no adapter can align these planes. For example, of these scientific cameras, only the Zelux can be configured for CS-mount lenses.

The position of the lens' focal plane is determined by a combination of the lens' FFD, which is measured in air, and any refractive elements between the lens and the camera's sensor. When light focused by the lens passes through a refractive element, instead of just travelling through air, the physical focal plane is shifted to longer distances by an amount that can be calculated. The adapter must add enough separation to compensate for both the camera's FFD, when it is too short, and the focal shift caused by any windows or filters inserted between the lens and sensor.

Flexiblity and Quick Fixes: Adjustable C-Mount Adapter
Passively cooled Kiralux and Quantalux cameras consist of a camera with SM1 internal threads, a window or filter covering the sensor and secured by a retaining ring, and an adjustable C-mount adapter.

A benefit of the adjustable C-mount adapter is that it can tune the spacing between the lens and camera over a 1.8 mm range, when the window / filter and retaining ring are in place. Changing the spacing can compensate for different effects that otherwise misalign the camera's sensor plane and the lens' focal plane. These effects include material expansion and contraction due to temperature changes, positioning errors from tolerance stacking, and focal shifts caused by a substitute window or filter with a different thickness or refractive index.

Adjusting the camera's adapter may be necessary to obtain sharp images of objects at infinity. When an object is at infinity, the incoming rays are parallel, and location of the focus defines the FFD of the lens. Since the actual FFDs of lenses and cameras may not match their intended FFDs, the focal plane for objects at infinity may be shifted from the sensor plane, resulting in a blurry image.

If it is impossible to get a sharp image of objects at infinity, despite tuning the lens focus, try adjusting the camera's adapter. This can compensate for shifts due to tolerance and environmental effects and bring the image into focus.

Why can the FFD be smaller than the distance separating the camera's flange and sensor?

Refraction through an optical filter or an window shifts the focal plane.
Click to Enlarge

Figure 9: Refraction causes the ray's angle with the optical axis to be shallower in the medium than in air (θm vs. θo ), due to the differences in refractive indices (nm vs. no ). After travelling a distance d in the medium, the ray is only hm closer to the axis. Due to this, the ray intersects the axis Δf beyond the f point.;

When their flange focal distances (FFD) are different, the camera's sensor plane and the lens' focal plane are misaligned, and focus cannot be achieved for images at infinity.
Click to Enlarge

Figure 11: Tolerance and / or temperature effects may result in the lens and camera having different FFDs. If the FFD of the lens is shorter, images of objects at infinity will be excluded from the focal range. Since the system cannot focus on them, they will be blurry.
When their flange focal distances (FFD) are the same, the camera's sensor plane and the lens' focal plane are perfectly aligned, and focus can be achieved for images at infinity.
Click to Enlarge

Figure 10: When their flange focal distances (FFD) are the same, the camera's sensor plane and the lens' focal plane are perfectly aligned. Images of objects at infinity coincide with one limit of the system's focal range.

Flange focal distance (FFD) values for cameras and lenses assume only air fills the space between the lens and the camera's sensor plane. If windows and / or filters are inserted between the lens and camera sensor, it may be necessary to increase the distance separating the camera's flange and sensor planes to a value beyond the specified FFD. A span equal to the FFD may be too short, because refraction through windows and filters bends the light's path and shifts the focal plane farther away.

If making changes to the optics between the lens and camera sensor, the resulting focal plane shift should be calculated to determine whether the separation between lens and camera should be adjusted to maintain good alignment. Note that good alignment is necessary for, but cannot guarantee, an in-focus image, since new optics may introduce aberrations and other effects resulting in unacceptable image quality.

A Case of the Bends: Focal Shift Due to Refraction
While travelling through a solid medium, a ray's path is straight (Figure 8). Its angle (θo ) with the optical axis is constant as it converges to the focal point (f ). Values of FFD are determined assuming this medium is air.

When an optic with plane-parallel sides and a higher refractive index (nm ) is placed in the ray's path, refraction causes the ray to bend and take a shallower angle (θm ) through the optic. This angle can be determined from Snell's law, as described in the table and illustrated in Figure 9.

While travelling through the optic, the ray approaches the optical axis at a slower rate than a ray travelling the same distance in air. After exiting the optic, the ray's angle with the axis is again θo , the same as a ray that did not pass through the optic. However, the ray exits the optic farther away from the axis than if it had never passed through it. Since the ray refracted by the optic is farther away, it crosses the axis at a point shifted Δf beyond the other ray's crossing. Increasing the optic's thickness widens the separation between the two rays, which increases Δf.

To Infinity and Beyond
It is important to many applications that the camera system be capable of capturing high-quality images of objects at infinity. Rays from these objects are parallel and focused to a point closer to the lens than rays from closer objects (Figure 9). The FFDs of cameras and lenses are defined so the focal point of rays from infinitely distant objects will align with the camera's sensor plane. When a lens has an adjustable focal range, objects at infinity are in focus at one end of the range and closer objects are in focus at the other.

Different effects, including temperature changes and tolerance stacking, can result in the lens and / or camera not exactly meeting the FFD specification. When the lens' actual FFD is shorter than the camera's, the camera system can no longer obtain sharp images of objects at infinity (Figure 11). This offset can also result if an optic is removed from between the lens and camera sensor.

An approach some lenses use to compensate for this is to allow the user to vary the lens focus to points "beyond" infinity. This does not refer to a physical distance, it just allows the lens to push its focal plane farther away. Thorlabs' Kiralux™ and Quantalux® cameras include adjustable C-mount adapters to allow the spacing to be tuned as needed.

If the lens' FFD is larger than the camera's, images of objects at infinity fall within the system's focal range, but some closer objects that should be within this range will be excluded. This situation can be caused by inserting optics between the lens and camera sensor. If objects at infinity can still be imaged, this can often be acceptable.

Not Just Theory: Camera Design Example
The C-mount, hermetically sealed, and TE-cooled Quantalux camera has a fixed 18.1 mm spacing between its flange surface and sensor plane. However, the FFD (f ) for C-mount camera systems is 17.526 mm. The camera's need for greater spacing becomes apparent when the focal shift due to the window soldered into the hermetic cover and the glass covering the sensor are taken into account. The results recorded in the table beneath Figure 9 show that both exact and paraxial equations return a required total spacing of 18.1 mm.

Can you better specify the main differencies between the CS2100M-USB and the CC215MU? In particular what is the difference in terms of readout noise and dark current
YLohia  (posted 2020-09-22 09:30:45.0)
Thank you for contacting Thorlabs. The readout noise is not strongly temperature dependent, hence the values are essentially the same and are specified as such. Dark current is very strongly temperature-dependent, and the most obvious impact of cooling is the reduction of hot pixels in the CC251MU. However, those are outliers, and would not be represented a mean dark current measurement. The dark current, when the CC215MU's cooler is energized and the camera is at equilibrium at a 20 deg C ambient temperature, is approximately 0.18 electrons per pixel per second.

How exactly is the hardware binning achieved? Is the mean of the pixels calculated or are the values simply added, forgoing the possibility to use binning under conditions where the total light exposure on the binned pixels exceeds the well depth of a single pixel?
tfrisch  (posted 2017-11-15 04:19:26.0)
Hello, thank you for contacting Thorlabs. The binning is performed on-camera in the digital domain, since charge-domain binning is not possible. It is a sum, not an average, so total light exposure should be monitored to avoid saturation.

tfrisch  (posted 2017-10-05 02:30:14.0)
Hello, thank you for your feedback. You can use the below data. This is changing the region of interest rather than binning. sCMOS does not have on-chip binning like some CCD cameras, so binning will not increase frame rate. Decreasing the region of interest will decrease field of view while preserving resolution. I will also send it to you directly by email.

Thorlabs offers four families of scientific cameras: Zelux™, Kiralux®, Quantalux®, and Scientific CCD. Zelux cameras are designed for general-purpose imaging and provide high imaging performance while maintaining a small footprint. Kiralux cameras have CMOS sensors in compact, passively cooled housings and are available with monochrome, color, NIR-enhanced, or polarization-sensitive sensors. The polarization-sensitive Kiralux camera incorporates an integrated micropolarizer array that, when used with our ThorCam™ software package, captures images that illustrate degree of linear polarization, azimuth, and intensity at the pixel level. Our Quantalux monochrome sCMOS cameras feature high dynamic range combined with extremely low read noise for low-light applications. They are available in either a compact passively cooled housing or a hermetically sealed TE-cooled housing. We also offer scientific CCD cameras with a variety of features, including versions optimized for operation at UV, visible, or NIR wavelengths; fast-frame-rate cameras; TE-cooled or non-cooled housings; and versions with the sensor face plate removed. The tables below provide a summary of our camera offerings.

Passively Cooled 2.1 Megapixel sCMOS Camera

  • Fanless Passive Thermal Management
  • Compact Housing: 2.77" x 2.38" x 1.88" (70.4 mm x 60.3 mm x 47.6 mm)
  • Compatible with 30 mm Cage System
  • SM1-Threaded (1.035"-40) Aperture with Adapter for Standard C-Mount (1.000"-32) Compatibility
  • Ships with USB 3.0 Cable

The CS2100M-USB Quantalux camera features a compact design that is engineered to provide passive thermal management for the sensor, reducing dark current without need for a cooling fan or thermoelectric cooler. When imaging conditions present high light levels and require short exposure times (less than 500 ms), the passively cooled CS2100M-USB camera is generally sufficient. We strongly recommend the TE-cooled CC215MU camera for applications with low light levels requiring an exposure greater than 500 ms.

The position of the 2/3" format, monochrome sCMOS sensor is indicated by an engraved line on the top of the camera body. The included clear window, which is AR coated for 400 - 700 nm, can be removed and replaced by another Ø1" (Ø25 mm) optic. When using the C-mount adapter, the maximum optic thickness is 0.050" (1.270 mm); otherwise the maximum optic thickness is 0.173" (4.4 mm). Please note that dust and debris may collect on the sensor face plate while the clear window is removed. Care must be taken when cleaning this face plate to avoid damaging the sensor.

A C-mount (1.000"-32) adapter with an adjustable flange focal range of ±1.5 mm is factory installed for out-of-the-box compatibility with many microscopes, machine vision camera lenses, and C-mount extension tubes. Removing this adapter exposes SM1 (1.035"-40) threading that can be used to attach a Ø1" Lens Tube. The camera can be connected to our 30 mm cage system via four 4-40 mounting holes on the front of the housing. Two 1/4"-20 tapped holes on opposite sides of the housing provide compatibility with imperial Ø1/2" Posts and many standard tripod mounts. These flexible mounting options and the compact size make this camera the ideal choice for integrating into custom-built imaging systems as well as those based on commercial microscopes.

Hermetically-Sealed, Cooled 2.1 Megapixel sCMOS Camera

  • Fanless Thermoelectric Cooling
  • Housing Dimmensions: 4.29" x 4.13" x 4.12" (109.0 mm x 104.8 mm x 104.8 mm)
  • Compatible with 60 mm Cage System
  • Factory Installed Adapter for Standard C-Mount (1.000"-32) Compatibility
  • Ships with USB 3.0 Cable and AC-DC Power Supply

The CC215MU hermetically sealed cooled Quantalux camera is designed with a thermoelectrically cooled chamber inside a large external heat sink to actively cool the
sensor and reduce dark shot noise. This camera is recommended for applications with low light levels requiring an exposure time greater than 500 ms. For high light levels requiring short exposure times (less than 500 ms), the passively cooled CS2100M-USB camera is generally sufficient.

The position of the monochrome, 2/3" format sCMOS sensor is approximately in line with the four front 1/4"-20 mounting holes, one located on each side of the housing. A removable C-mount adapter on the front end of the camera holds a clear protective window, which is AR coated for 400 - 700 nm, and can be removed and replaced by another Ø1" (Ø25 mm) optic up to 0.079" (2.0 mm) thick. Please note that dust and debris may collect on the hermetic chamber glass covering while the clear window is removed. Care must be taken when cleaning this covering to avoid scratching or other damage to the glass.

The factory installed C-mount (1.000"-32) adapter has a fixed flange focal distance and provides out-of-the-box compatibility with many microscopes, machine vision camera lenses, and C-mount extension tubes. The camera can be connected to our 60 mm cage system via four 4-40 mounting holes on the front of the housing, and 1/4"-20 tapped holes on the sides are provided for use with our imperial Ø1" pedestal or pillar posts. These flexible mounting options provide compatibility with commercial microscopes and support integration into home-built imaging systems.

Scientific Camera Optional Accessories

TSI-IOBOB2 Diagram
Click for Details

A schematic showing a TSI-IOBOB2 connected to an Arduino to trigger a compact scientific camera.

These optional accessories allow for easy use of the auxiliary port of our compact scientific (sCMOS & CMOS) or scientific CCD cameras. These items should be considered when it is necessary to externally trigger the camera, to monitor camera performance with an oscilloscope, or for simultaneous control of the camera with other instruments.

For our USB 3.0 cameras, we also offer a PCIe USB 3.0 card and extra cables for facilitating the connection to the computer.

Auxiliary I/O Cable (8050-CAB1)
The 8050-CAB1 is a 10' (3 m) long cable that mates with the auxiliary connector on our scientific cameras* and provides the ability to externally trigger the camera as well as monitor status output signals. One end of the cable features a male 12-pin connector for connecting to the camera, while the other end has a male 6-pin Mini Din connector for connecting to external devices. This cable is ideal for use with our interconnect break-out boards described below. For information on the pin layout, please see the Pin Diagrams tab above.

*The 8050-CAB1 cable is not compatible with our former-generation 1500M series cameras.

Interconnect Break-Out Board (TSI-IOBOB)
The TSI-IOBOB is designed to "break out" the 6-pin Mini Din connector found on our scientific camera auxiliary cables into five SMA connectors. The SMA connectors can then be connected using SMA cables to other devices to provide a trigger input to the camera or to monitor camera performance. The pin configurations are listed on the Pin Diagrams tab above.

Interconnect Break-Out Board / Shield for Arduino (TSI-IOBOB2)
The TSI-IOBOB2 offers the same breakout functionality of the camera signals as the TSI-IOBOB. Additionally, it functions as a shield for Arduino, by placing the TSI-IOBOB2 shield on a Arduino board supporting the Arduino Uno Rev. 3 form factor. While the camera inputs and outputs are 5 V TTL, the TSI-IOBOB2 features bi-directional logic level converters to enable compatibility with Arduino boards operating on either 5 V or 3.3 V logic. Sample programs for controlling the scientific camera are available for download from our software page, and are also described in the manual (found by clicking on the red Docs icon below). For more information on Arduino, or for information on purchasing an Arduino board, please see www.arduino.cc.

The image to the right shows a schematic of a configuration with the TSI-IOBOB2 with an Arduino board integrated into a camera imaging system. The camera is connected to the break-out board using a 8050-CAB1 cable that must be purchased separately. The pins on the shield can be used to deliver signals to simultaneously control other peripheral devices, such as light sources, shutters, or motion control devices. Once the control program is written to the Arduino board, the USB connection to the host PC can be removed, allowing for a stand-alone system control platform; alternately, the USB connection can be left in place to allow for two-way communication between the Arduino and the PC. The compact size of 2.70" x 2.10" (68.6 mm x 53.3 mm) also aids in keeping systems based on the TSI-IOBOB2 compact.

USB 3.0 Camera Accessories (USB3-MBA-118 and USB3-PCIE)
We also offer a USB 3.0 A to Micro B cable for connecting our cameras to a PC. Please note that one USB3-MBA-118 cable is included with each USB 3.0 camera except the CC215MU cooled Quantalux camera. The CC215MU camera ships with an appropriate USB 3.0 cable and should not be used with the USB3-MBA-118. The USB3-MBA-118 cable measures 118" long and features screws on either side of the Micro B connector that mate with tapped holes on the camera for securing the USB cable to the camera housing. When operating USB 3.0 cameras it is strongly recommended that the Thorlabs-supplied USB 3.0 cable be used, with the retention screws securely fastened. Due to the high data rates involved, users may experience problems when using generic USB 3.0 cables.

Cameras with USB 3.0 connectivity may be connected directly to the USB 3.0 port on a laptop or desktop computer. USB 3.0 cameras are not compatible with USB 2.0 ports. Host-side USB 3.0 ports are often blue in color, although they may also be black in color, and typically marked "SS" for SuperSpeed. A USB 3.0 PCIe card is sold separately for computers without an integrated Intel USB 3.0 controller. Note that the use of a USB hub may impact performance. A dedicated connection to the PC is preferred.
