Thorlabs' scan lenses are telecentric objectives, which makes them desirable for use in laser imaging systems and laser scanning applications like Optical Coherence Tomography (OCT). These applications benefit from the flat imaging plane that telecentric objectives offer as a laser beam is scanned across the sample. A flat imaging plane minimizes image distortion, which in turn creates geometrically correct images without the need for extensive post-image processing. A telecentric scan lens also maximizes the coupling of the light scattered or emitted from the sample (the signal) into the detection system. In addition, the spot size in the image plane is nearly constant over the entire FOV (see Graphs tab), resulting in constant image resolution.

Thorlabs manufactures two families of scan lenses: the LSM series and the CLS-SL. Our LSM series is available with design wavelengths of 633, 850, 1050, or 1315 nm, while the CLS-SL scan lens' design was optimized for broadband imaging in the 400 - 750 nm range. The LSMxx scan lenses have an AR coating designed to minimize back reflections from broadband light sources with a central wavelength of 1315 nm (see plot below), which is a popular wavelength for OCT systems. For wavelengths outside of the effective wavelength range of these four lenses, Thorlabs also offers broadband variants (LSMxx-BB) that have an AR coating for the 800 - 1100 nm range. In addition, we offer a variant of the LSM03 for visible wavelengths (LSM03-VIS) with an AR coating for 400 - 700 nm.

In order to assist with the integration of the -BB scan lenses into OCT systems, several system parameters have been specified (see the Specs tab) at 850 nm and 1050 nm. However, the -BB scan lenses can be used with light sources throughout the 800 nm to 1100 nm range.

Scan Lens Schematic

  • Scanning Distance (SD): The SD is the distance between the galvo mirror pivot point and the back mounting plate of the objective. Since the LSM scan lenses are telecentric, the galvo mirror pivot point must be located at the back focal plane of the objective in order to maximize image resolution.

  • Pupil Size (EP): The size of the EP determines the ideal 1/e2 collimated beam diameter that should be used for the beam of light used to image the sample in order to maximize the resolution of the imaging system. All three LSM scan lenses have an EP 4 mm in diameter.

  • Working Distance (WD or LWD): The distance between the tip of the scan lens housing and the front focal plane of the scan lens is defined as the WD.

  • Depth of View (DOV): The DOV parameter reported for the LSM scan lenses corresponds to the distance between the parallel planes on either side of the front focal plane where the beam spot diameter is √2 greater than at the front focal plane.

  • Field of View (FOV): The FOV is the maximum size of the area on the sample that can be imaged with a resolution equal to or better than the stated resolution of the LSM scan lenses. In order to meet this specification the imaging system must be designed to properly utilize the LSM scan lenses in the system.

  • Parfocal Distance (PD): The PD is the distance from the scan lens mounting plane to the front focal plane of the LSM scan lenses.

  • Curvature (C): The curvature is the maximum distance between the front focal surface and an ideal plane.

  • Scan Angle (SA): The SA is the maximum allowed angle (in the X or Y direction) between the beam and the optical axis of an LSM scan lenses after being reflected off of the galvo mirror.

LSM Scan Lens Spot Size Calculation

If the incident beam is centered in the field of view of the scan lens, the resulting spot will circular. However, as the beam is moved off-axis, the spot will take on an elliptical shape. The plots below show the calculated spot width in the sagittal and tangential directions as a function of beam position or scan angle for a variety of wavelengths.

The beam was scanned along the x- or y- axis of the lens, and the resulting spot size was measured (see the Spot Dimensions drawing to the right for reference). The X-Axis Scan plots represent beam scans along the x-axis of the lens, with the beam position in the y direction held constant at zero. The Y-Axis Scan plots represent beam scans along the y-axis of the lens, with the beam position in the x direction held constant at zero. All mentions of the x and y axes in the plots refer to those of the scan lens.

The sagittal and tangential spot diameters were calculated at various scan angles and wavelengths (see the Scan Lens Axes drawing to the right for reference). When the spot is circular, the sagittal and tangential measurements are equivalent because they represent the diameter of that circle. When the spot is elliptical, the sagittal and tangential measurements differ as they represent the minor and major diameters of the ellipse. All mentions of the sagittal and tangential axes in the plots refer to those of the spot.

CLS-SL Scan Lens Transmission and Spot Size

The graphs below show the transmission and calculated spot diameter at the image plane of the CLS-SL scan lens. The spot size calculations are based on a 4 mm collimated beam at various scan angles and wavelengths covering the visible range. The diameter is calculated such that 87% of the light is encircled.

Thorlabs' scanning objective lenses were designed to improve the performance of Thorlabs' Swept Source and Spectral Domain OCT imaging systems. This type of objective lens is usually called a scan lens because a laser beam is scanned across the back aperture of the objective lens in order to form the image of the sample. Each position that the laser is scanned over corresponds to one point in the image formed. This approach results in a focal spot on the sample that is not, in general, coincident with the optical axis of the scan lens. In traditional lenses, this would result in the introduction of severe aberrations that would significantly degrade quality of the resulting image. However the LSM series of scan lenses were designed to create a uniform spot size and optical path length for the laser for every scan position, which allows a uniform, high-quality, image of the sample to be formed. Plots that show the spot size as a function of scan position can be seen by looking at the Graphs tab.

When designing an imaging system that uses an LSM scan lens it is important to accommodate the Design Wavelength, Parfocal Distance, Scanning Distance, Entrance Pupil, and Scan Angle specifications in order to maximize the image quality (see the Specs tab for scan lens specifications and definitions). For imaging systems with a single galvo mirror the center of the scan lens's entrance pupil must be coincident with the center of the galvo mirror. If the imaging system uses two galvo mirrors (one to scan in the X direction and one to scan in the Y direction) then the entrance pupil should be located between the two galvo mirrors. It is important to minimize the distance between the two galvo mirrors, because when the entrance pupil and beam steering pivot point are not coincident, the quality of the image is degraded. This is principally due to the variation in the optical path length as the beam is scanned over the sample. Below are schematics for an imaging system containing one and two galvo mirrors.

The maximum recommended separation between the two

Dear sir/madam, the zemax file of LSM05-BB seems to be the one of LSM05. Eventhough it is named correctly, after opening the title of the lens is LSM05 and the wavelength specified is 1315nm insted of the BBs 850nm & 1050nm. I would like to receive the correct ZMX file rather soon if possible. Sincerely Thomas Liebig

Response from Mike at Thorlabs: Thank you for your feedback. The scanning position is defined as the distance from the scanning mirror to the end of the externally threaded region on the scan lens housing. This can be seen in the “Application info” tab or in the enlarged image in the “Visible Scan Lens for Laser Scanning Microscopy” grouping. In a 4f optics system the distance from the tube lens to the objective will be f2, or the focal length of the tube lens. However, this is rarely the case in an imaging system. When the objective is moved from this position the scan lens will also have to shift to compensate for this. When the objective is moved further from the tube lens the scanning position will decrease, and vice versa. We are currently working on updating this presentation to make this more clear.

"The shorter the distance between the tube lens and the objective, the longer the scanning position." What is meant by "scanning position" in this statement? Isn't the scanning position determined by the working distance of the objective lens?

Response from Mike at Thorlabs: Thank you for your feedback. The mean spot size in the table within the “Specs” tab is valid for an entrance beam diameter of 8 mm. The graph is showing the spot size for a single mode fiber that is being collimated with an asphere. This provides an entrance beam diameter of approximately 4 mm. Both mean spot sizes are correct, but they are for different entrance beam diameters. We will update the website to make this more clear.

On the Specs tab in the "Scan Lenses for Laser Scanning Microscopy" page, the mean spot size for this lens is reported in the table "1315 nm OCT Scan Lenses" as 23.5um. However, in the graphs tab, the spot sizes shown for 1315nm are 65-67um. Is this an error? Could you confirm the mean spot size for this lens? Thank you.

  • For detailed specs, please refer to the Specs Tab.

The CLS-SL scan lens is designed for point-by-point laser scanning imaging in the visible wavelength range (400 - 750 nm). This scan lens, originally designed for Thorlabs' Confocal Laser Scanning Microscopy Systems, is now available for customers designing their own laser scanning systems. In these applications, we recommend utilizing the scan lens with our ITL200 tube lens and one of our objectives. The CLS-SL has a 70 mm effective focal length.

This scan lens has external SM2 (2.035"-40) threads on both ends, making it easy to incorporate into customized microscopy systems. Please note that even though the CLS-SL has a symmetric housing, it is not bi-directional. When the housing's engraving is right-side-up, the light should enter the lens from the top.

The CLS-SL scan lens is designed for variable scanning positions. As illustrated in the enlarged drawing to the right, the optimal scanning position should be determined based on the distance between the tube lens and the objective lens. The shorter the distance between the tube lens and the objective, the longer the scanning position.

The image to the left helps to show the relationship between the scan distance and the objective distance. In a perfect 4f optical system (using the CLS-SL), d1 = 52 mm (minimum scan distance) and d2 = f2. However, in many practical cases the system is slightly deviated from this perfect alignment. For instance, in many commercial microscopes, the objective distance (d2) is not the same as the focal length (f2), so there may be a need to adjust distances. The figure to the right shows the scan and objective distance moved by some small distance δ1 and δ2, respectively. The relationship between these values is δd1 = -δd2*(f1/f2)2.

LSM05 with GAS012
  • Mounting Bracket and Adapter for Integrating our LSM05 Telecentric Scan Lens with our GVS012(/M) Large Beam Galvo Mirror Pair
  • GAS0123 Thread Adapter (Sold Below) Required for Attaching LSM05 Lens
  • Removable 30 mm Cage- and SM1 Thread-Compatible Input Plate
  • Compatible with Imperial or Metric Breadboards and Optical Tables

The GAS012 mounting bracket allows for the integration of our LSM05 Telecentric Scan Lens with our GVS012 or GVS012/M galvanometer mirror pairs. It also allows the complete assembly to be integrated with optical table or breadboard-based optomechanical setups. To use the GAS012 mounting bracket, the GAS0123 thread adapter (also sold below) must also be purchased. This places the lens at the recommended distance from the second galvo mirror.

The input light port is a plate with SM1 (1.035"-40) threading for Ø1" lens tube compatibility and four Ø6 mm cage rod holes for 30 mm cage system integration. The GAS012 bracket has a bottom mounting surface with eight #8 (M4) and nine 1/4" (M6) through holes, spaced at 12.6 mm (0.496") and 25.2 mm (0.99"), respectively, for compatibility with both imperial and metric breadboards and optical tables. When mounted, the GVS012(/M) galvo mirror pair does not sit directly on this surface, allowing all of the through holes to be used for table or breadboard mounting.
