These stepper-motor-driven filter wheels are designed for use in a host of automated applications including color CCD photography, fluorescence microscopy, and photometry. Each unit consists of a motorized housing and a preinstalled filter wheel with either 6 positions for Ø1" (Ø25 mm) optics or 12 positions for Ø1/2" (Ø12.5 mm) optics. Filter wheels of either type can also be purchased separately and installed by the user.
The housing contains two ports equipped with internal SM1 (1.035"-40) threading on both sides to accommodate our Ø1" lens tubes; each port is also surrounded by four 4-40 tapped holes on both sides for compatibility with our 30 mm cage systems, as shown in the image to the right. The 12-position motorized filter wheels for Ø1/2" optics (Item #'s FW212C and FW212CNEB) also come with four SM1A6FW adapters for converting the two SM1-threaded ports to an internal SM05 (0.535"-40) thread.
Interchangeable Filter Wheels
Additional 6- or 12-position filter wheels are available below with or without preloaded absorptive, uncoated ND filters. The motorized housings are compatible with both types of wheels. Refer to the animation below to see how to switch between the different filter wheel options.
Manual or Remote Operation
The filter position can be manually selected using the push button arrows on the top of the unit or remotely selected using the USB 2.0 interface, BNC input, or RS-232 connection (please see chapter five of the manual). The BNC input rotates the filter wheel when a TTL-level signal is applied. This BNC connection can also be configured as an output trigger in the software. An easy-to-read display indicates the filter selection. The display intensity can be adjusted, making this filter wheel appropriate for light-sensitive environments.
Automation of filter sequences is available through the USB 2.0 or RS-232 interfaces along with a simple-to-use GUI application program. A simple command language facilitates the filter selections and the retrieval of filter status. For driver software, as well as an SDK manual and sample code for LabVIEW™ and Visual C++, please see the Software tab. Older versions of the motorized housing sold before April 23, 2014 may require a firmware update, which is also available for download from the Software tab.
Mounting Options
As described above, each filter wheel port is internally SM1 threaded, allowing for easy connection to externally SM1-threaded optomechanics. Four 4-40 taps are also centered around each port, making the filter wheel compatible with our 30 mm cage systems. Thorlabs offers an extensive selection of adapters for mating our SM1-compatible components to other threads, such as C-mount, microscope, and telescope standards. The bottom of the housing features one 8-32 tap, one M4 tap, two 1/4"-20 taps, and two M6 taps, creating a multitude of options for mounting the filter wheel housing to a Ø1/2" or Ø1" post.

I would liike to know if the software and APIs are compatible with Linux Environment.
Thank you in advance,
Best regards,
Claudia YLohia
(posted 2019-07-02 11:29:57.0) Hello Claudia, thank you for contacting Thorlabs. The USB port connection for these filter wheels uses an FTDI chip, for which you can find drivers online here: http://www.ftdichip.com/Drivers/VCP.htm.
You will not need a specific driver if you use the RS-232 connection. Unfortunately, we don't officially support Linux for this software currently, but you can refer to the serial port commands and settings in the manual for more information in order to write your program. Jean-Baptiste Le Bouquin
(posted 2019-04-13 16:18:20.67) Hi, we need a filter wheel to load either 1" circular or 1"x1" square optics. Is it possible to remove one side of the cover of FW102C, in order to screw an adaptor for 1"x1" square optics ? Thanks. YLohia

(posted 2019-02-11 11:35:04.67) Hi, I'm having trouble with getting the FW212C filter wheel to register 12 positions with micromanager software rather than 6. which is the default. I'm using the Thorlabs driver. The wheel registers 12 positions in the Thorlabs software, and operates normally. llamb
(posted 2019-02-22 03:44:06.0) Thank you for contacting Thorlabs. While we do not officially support Micro-Manager at this time, the Set Position Count command should be set to pcount=12. I have reached out to you directly to try and troubleshoot further. carlo.desanti
(posted 2018-10-22 13:35:38.39) Dear Thorlabs technical support,
is the filter wheel able to operate only in vertical position (i.e. as in the picture on the website) or also in horizontal position (e.g. connected directly to the optical path of a microscope, with the light coming from the floor and going towards the ceiling)? In the latter case, would its weigth be a problem?
Thanks, best regards. YLohia
(posted 2018-10-24 04:30:04.0) Hello, thank you for contacting Thorlabs. The mounting orientation (horizontal vs vertical) should not impact the performance of the filter wheel. trearick
(posted 2018-08-14 12:47:06.31) I need to control the filter wheel from matlab, which I could do if a 64-bit version of the windows driver were available. I see people asked for it many years ago...is one available??? YLohia
(posted 2018-08-15 02:27:36.0) Hello, thank you for contacting Thorlabs. If the latest version (4.2.0) of the software is downloaded from the webpage, then there will be a folder under the following location:

(posted 2018-04-04 09:50:09.0) Thank you for your feedback. We'd be happy to help troubleshoot this issue you are seeing where the filter wheels reset their position and move positions after several hours.
If possible we will need to know more details about how you are controlling these units such as are you controlling them simply through the FW GUI software using command sequences, are you sending commands using C++, Labview or triggering with a TTL pulse? I will contact you directly to help troubleshoot your filter wheel. For more assistance regarding technical product support please contact us at techsupport@thorlabs.com or 973-300-3000 pblackburn
(posted 2018-01-10 12:38:35.317) We have several of these filter wheels on hand and the internal wheel wobbles on all of them. No matter how tight the thumb screw is tightened, the filter wheel's bearings are never fully clamped by the two sides of the housing, allowing the plane of the wheel to wobble. This is causing issues for us, as it couples mechanical vibration to optical signal noise. I'm surprised that no one else has complained about this. Do you have suggestion to address this? We have some ideas but would like to hear what Thorlabs has to say.
Thank you. nbayconich
(posted 2018-05-08 09:04:09.0) Thank you for your feedback. In the old design we were installing shims underneath the bearings to compensate for dimensional tolerances. In March 2013 we updated the design and the use of shims was not required anymore. Chances are these filter wheels were purchased before the design update and in these units the shims were not installed properly. We can of course return and repair any of these filter wheels that have been experiencing this problem.
I will contact you directly to help troubleshoot these parts. cimrova
(posted 2017-05-16 13:36:24.637) I have FW102B and FW102C. For programming of FW102B I use command pos=1 to set position of the filter and pos? asking the position, which I send to the port.

I waste a lot of time waiting for the filter wheels reaching the next position. Some changes take more time - therefore I have to wait at least for the maximum change time (automated system).
Is there an option to ask "reached position?" or "Moving?". If the device would be able to tell when its moving is finished, I wouldn't waste any time waiting. tfrisch

Vorschlag: Erweiterung der Elektronik, so dass der den Motor auch über USB betrieben werden kann. Nötigenfalls, da über USB nicht viel Leistung bezogen werden kann, den Motor(anderer Motor/Getriebe) langsamer laufen lassen.
Oder nur USB -> langsam
Mit Stromversorgung -> schnell

You can try updating the firmware to the latest version; however, if the wheels really have several 100,000 cycles on them then they are getting very close to the end of their life and the firmware update will not help. The loss of communication and the need to cycle the power is an indication that the FW102B is not completing the commanded move. This occurs more frequently as the wheel ages. The latest firmware is a little more robust in trying to force the wheel to complete the move, but even this does not work all the time. The FW102C will not have this issue, as its life time is much longer than that of the FW102B.I will contact you directly for further support. carsten.schmidt

I am frequently experiencing the same problems as smcmanus and guspank: I am loosing the connection to filterwheel after a couple of hours. My workaround was to include a relay, which switched off the power to the FW. After 10 seconds power was restored and everything was fine again. Now Ive got a couple of questions:
1) I have one system, where this doesnt work anymore. It can take hours or even a reboot to reestablish the communication. The specific fw102b dates back to 06/2009, application s/w update from vs1.0 to vs1.02 (my newest version) didnt help. The fw worked more or less fine with the error occuring only once every three months, but now it occurs everyday. In an older post I read a firmware update might help? My issues got worse after I changed the instruments setup (more data is forced through the USB ports). Three other fw102b work fine with the new setup.
LabView Errors are:
Driver Status: (Hex 0xBFFF0015) (time out?) and (Hex 0xBFFA1190) The session handle is not valid.
2) The fw was excessively used (hundred thousands of revolutions). Has it possibly reached the end of its expected lifetime? How do I notice if a fw does?
3) My FW102C are realtively new. Do I have to expect the same issues? Until now everything works fine!

You might have an issue with the firmware in the wheel not retaining updated info in the EPROM. We will send you update program to fix it. Unzip the file into some directory and then with the wheel attached and turned on but no applications running, run Reprogram.exe. This should update the firmware.
If you should change the baud rate, once you reconnects to the wheel at the new baud rate, you should send the "save" command. If not, when you cycles power to the wheel it will revert back to the original baud rate. cdorrer
(posted 2009-10-28 12:54:31.0) The baud rate for the serial port switches back to 9600 baud even after changing it to 115200 and saving the change in the Automation Explorer. If the baud rate is set through the Windows Hardware control panel, a problem occurs because the VISA rate (9600) is different from the Windows rate (115200). Additionally, sessions open via the Automation Explorer or directly with Labview do not operate (e.g. generate a Framing Error). This occurs on two different computers. leichner
(posted 2009-06-23 09:16:16.0) A FTDI type of device needs to have a driver installed. This is what enables RS232 protocol to work with a USB port. They are both serial but the protocol is different. Typically Windows assigns a USR type of interface (RS232 to USB) to COM3 or COM7. You can force the COM7 assignment to COM3. As long as the hardware is connected the port assignment remains. Once the a device is disconnected the port setting can change next time around. The application software must have the option to negotiate port settings. If a fixed dedicated port is necessary then the argument not to do away with RS232 is very strong. andrew.litak

(posted 2009-04-16 11:23:33.0) A response from Greg at Thorlabs to smcmanus: Thank you for your feedback on the FW102B. There are a few different possibilities that may be causing the filter wheels to stall. First, there may be too many devices connected to your computer as USB is shared. If you are using a USB hub, please try connecting the filter wheels directly to your computer. We have seen issues with certain hubs not working as well as others when multiple devices are connected.
If you send commands too quickly to the filter wheels, you may fill up the memory buffer. This can stall the system. If you send commands only after the wheel has completed a move, this will not be an issue. The wheel takes roughly 600 ms to change position, thus sending commands after a greater interval of time is ideal.
A member of our Technical Support group has been put in contact with you to ensure that we identify the source of your issue and resolve it. smcmanus

Based on the information you provided in your post, I would suggest that you try the following: (1) Ensure that your light is striking the filter wheel at normal incidence. (2) Ensure that all filters are mounted such that the incident beam is also normal to their surfaces (Use canned air to clean out any dust particles that may be in the filter wheel slots). (3) Although our standard retaining rings generally produce good results, you could consider switching to our stress-free retaining rings (SM1LTRR).

Can you recommend anything to improve this? For one, Im surprised theres no O-ring with each filter to ensure consistent mounting. Tyler
(posted 2008-06-26 16:42:22.0) A response from Tyler at Thorlabs to jjohnson: I will have an applications engineer start a dialog with you about this issue. However, in short, each filter wheel has a unique USB id. When a PC sees a new USB device for the first time it creates a registry key where it associates the USB id with a serial port. The next time it sees that device, it attempts to assign the same port to the device as the previous time. This works fine unless some other device has been attached that is now assigned to that port. In that case, the next available port is assigned to the device. So if you attach 5 filter wheels, and there are no new devices taking up any of the original 5 ports, then everything should be fine even if you attach them to different USB ports or use a different USB hub. jjohnson
(posted 2008-06-25 13:16:24.0) Hi,
My application will use up to 5 filter wheels (so sometimes a usb hub will be used).
What would be the process to assure that each filter wheel gets the same COM port each time the system comes up? (users would have a hard time with this!)
Thanks,

- 6-Position Motorized Wheel for Ø1" (Ø25 mm) Optics
- Maximum Optic Thickness Accepted: 0.25" (6.35 mm)
- Available With (Item # FW102CNEB) or Without (Item # FW102C) Preloaded Absorptive ND Filters
- Includes Two SM1CP2 SM1-Threaded End Caps and Six SM1RR Retaining Rings
- Filter Wheels are Interchangeable
The FW102C and FW102CNEB 6-Position Motorized Filter Wheels are designed for Ø1" (Ø25 mm) optics and are sold without filters or preloaded with neutral density (ND) filters, respectively. Please see the table to the right for the included uncoated absorptive ND filters.
Each motorized filter wheel contains two internally SM1-threaded apertures, labeled A for the 210° position and B for the 0° position. The A/B switch allows one of the labeled ports to be designated as the primary port, and the filter wheel will rotate with respect to the primary port chosen. Filters can be manually selected using the push button on top of the unit or automated using the provided software. The current position of the filter wheel with respect to the selected port is shown on the display window. The brightness of this display can be adjusted with a small screwdriver at the hole labeled DIM, making this filter wheel appropriate for use in light sensitive applications.
The filter wheel included with each unit is fully interchangeable (see the animation in the Overview tab) by removing the front cover of the housing. A selection of 6- and 12-position filter wheels, with and without preloaded ND filters, is available below.
Two SM1CP2 SM1-threaded end caps and six SM1RR Retaining Rings are provided with the filter wheel; additional quantities can be purchased separately. A region-specific power cord is selected at the time of purchase.

The 6- and 12-Position Filter Wheels Are Also Available with Preloaded ND Filters (See Table to the Right)
- Additional, Interchangeable Filter Wheels for the Motorized Housings Above
- 6- and 12-Position Filter Wheels for Ø1" (25 mm) and
Ø1/2" (12.5 mm) Optics, Respectively - Maximum Optic Thickness: 0.25" (6.35 mm)
These 6- and 12-Position Filter Wheels are available with or without preloaded, uncoated, absorptive ND filters. They are compatible with our entire line of motorized filter wheels shown above. The 6-position wheels are designed to accept Ø1" (25 mm) optics while the 12-position wheels are designed for Ø1/2" (12.5 mm) optics. The filters included with the preloaded wheels are listed in the table to the right.
Step-by-Step Switching Directions
The Overview tab contains an animation that shows how to switch between a 6- and 12-position filter wheel. To switch between two filter wheels with the same number of positions, turn off the power to the motorized filter wheel, unscrew the thumbscrew on the front of the housing, and remove the front cover. The filter wheel can then be removed and another wheel can then be inserted. To switch between a 6-position and a 12-position wheel, follow the same process. However, when the front cover is reattached, you must adjust the settings of the motorized filter wheel to the new number of positions. This is done by holding the top two arrow buttons for approximately three seconds and then changing the filter position value to either six or twelve.
