Fixed Microscope Slide Holder
The MAX3SLH fixed slide holder is compatible with microscope slides or test targets as well as any rectangular optic that has a minimum width of 1.73" (44.0 mm). It is directly compatible with our 3-axis flexure stages (see image below), as well as other translation stages that have 1/4"-20 (M6) taps on 2" (50.8 mm) centers.

Microscope Slide Spring Clips
SLH1(/M) Microscope Slide Spring Clips can be attached to any stage with 8-32 (M4) tapped holes to hold microscope slides or test targets of various sizes. Each clip is 2.51" (63.7 mm) long with a 0.20" (5.1 mm) wide tip and can be rotated 360° for easy access to slides. Three dowel pins are included to align slides over the central aperture of our XYR1(/M) and XYT1(/M) Translation Stages.

Four-Position Microscope Slide Holder
The C4SH01 multiple slide holder supports up to four 25 mm x 75 mm microscope slides per tray, enabling fast analysis of multiple cultures. To support large-sample automated data collection, this microscopy slide tray has been designed to work with most common robotic plate readers. It is directly compatible with any microscope stage insert that accepts standard multiwell microplates, such as Thorlabs’ z-axis piezo stage, XY scanning stage (when the MLS203P1 plate adapter is also installed), or imaging cytometers. The C4SH01 is not compatible with the 26 mm x 76 mm slides sold by Thorlabs.

Slide Holder Mount
The XYF1(/M) Slide Holder Mount is designed to provide stable, self-contained translation when mounting our microscope slidestest targetsfilters, or any rectangular optic 1" (25.4 mm) to 3" (76.2 mm) wide and up to 0.16" (4 mm) thick. There are two actuators on the side of the mount that allow for manual positioning of the optic over a 50 mm (1.97") x 30 mm (1.18") area. To secure the optic, the mount has four nylon-tipped setscrews within two mounting arms that can be adjusted with a 5/64" (2 mm) hex.

I have recently received the new XYF1 and also own the previous model. I find the new model to be stiffer to operate than the original (the actuators are stiffer). Also I feel a periodic resistance when rotating the horizontal axis actuator: that is to say, if one plotted the torque required to rotate the actuator vs distance traveled , the torque would follow a sine wave like pattern rather than be constant. In an attempt to improve the new model's operation I applied some grease on the lead screw and rack and pinion (the old model had grease, the new one not). This helped but didn't completely solve either issues. Could you please comment on the use of grease (a dry mechanism is a clear advantage as it prevents any contamination of the test target, but it has to be smooth), and is there anything I could adjust in order to improve operation?

Thank you for your feedback. This new XYF1 filter holder was designed to be greaseless to both prevent contamination of the test target and to also prevent exposed components from sticking over time. The design is naturally stiffer than the previous filter holder. If you see uneven rotation torque that inhibits your application, you can consider removing the brass translation locking screw and applying grease in the axle. Our mechanics team is now more closely monitoring the feel of these adjusters for future production. I will reach out to you directly to discuss further.

Do you have any XYFM1 still in stock? I applied for funding to build a microscopy lab for the undergraduate class that I teach based on that model, and the new XYF1 is almost double in price and no longer fits in my budget. I only need one! I have a new lab discount, so I was counting on only spending $188 on this part.

Hello, thank you for contacting Thorlabs. We are sorry to hear that the new XYF1 does not fit in your budget. We do still have a few units of the obsoleted item in our inventory. I will reach out to you via email with more information.

BEWARE! XYFM1 Translating Filter Mount does not work with the larger (100mm) ND filters as the image might fool you into thinking (!
tfrisch  (posted 2017-03-13 05:29:40.0)
Hello, thank you for contacting Thorlabs. The maximum filter width for XYFM1 is 3" (76.2 mm). Please note that this is listed in the image caption, item name, and technical drawing. I will contact you directly about solutions for your application.

I second the idea (suggested below) of offering adapters for various cover slips sizes (especially 22 mm x 22 mm).
tfrisch  (posted 2017-01-26 05:52:09.0)
Hello, thank you for your feedback. I've posted your need in our internal engineering forum. If you have details on the dimensions of the slip, including thickness, please contact us directly at to discuss them. Thank you.

Hi can I put a Motorized Actuator on XYFM1/M one of the axes. (I also vote for a slimmer version with only X translation)
jlow  (posted 2016-10-24 03:05:58.0)
Response from Jeremy at Thorlabs: Thank you for your feedback. Unfortunately we do not have a motorized actuator for the XYFM1(/M) at the moment.
user  (posted 2016-09-22 14:11:35.207)
Addition of a tapped hole on the back face of the mount would allow it to hold a microscope slide vertically like the xy stage can.
jlow  (posted 2016-09-23 02:46:17.0)
Response from Jeremy at Thorlabs: Thank you very much for your feedback. We will look into implementing this.
loo  (posted 2016-02-05 15:05:09.033)
Hi, it would be nice if there was a bigger a more simple version of this product. Basically scrap the Y axis, make the X axis 100mm long and enlarge the optics bed to 25 x 100 x 4 mm, so we can fit a couple NDL-25C-4s. That's the setup I'been using for years, and it's annoying to order it to several companies every time I need one more. Also if the micrometric screw was easily motorizable it would be awesome.

Response from Bweh at Thorlabs USA: Thanks for the feedback. We will review your suggestion.
anthony.kaye  (posted 2014-04-07 09:10:24.09)
A large number of our samples are small -- perhaps 10 mm x 10 mm; in some cases, we've had to cut them from larger substrates (so the edges aren't perfect). We would really like it if something like the XYFM1 could handle smaller (and/or oddly-shaped) samples.
cdaly  (posted 2014-04-10 11:16:34.0)
Response from Chris at Thorlabs: Unfortunately a 10 mm sample would be a bit too small for us to customize this mount for. The clamping fingers would end up covering the better part of the sample. Might it be possible to use the CH1A on a translation stage to hold your sample?
ben_mangum  (posted 2013-05-15 16:51:51.62)
It would be great if you could offer extra spring clips separately. Also, adapters allowing mounting of various sizes of coverslips would be great too.
tcohen  (posted 2013-05-16 16:27:00.0)
Response from Tim at Thorlabs: Thank you for sharing your idea. We’ll look into adapters and we can certainly provide the extra spring clips separately if desired. I will contact you directly to provide these.

A channel allows for translation of the lockable support arms for accommodating optics with different widths.
  • Compatible with 1" (25.4 mm) to 3" (76.2 mm) Wide Rectangular Optics
  • Maximum Optic Thickness of 0.16" (4 mm)
  • 50 mm (1.97") Horizontal Travel and 30 mm (1.18") Vertical Travel
  • Each Axis Includes a Vernier Scale that Provides 100 µm Resolution
  • 8-32 (M4) Tapped Holes Support Six Post-Mounted Orientations
  • Four Nylon-Tipped Setscrews Secure the Optic Between Two Mounting Arms

Thorlabs' XYF1(/M) Test Target Positioning Mount accepts 1" (25.4 mm) to 3" (76.2 mm) wide rectangular optics up to 0.16" (4 mm) thick. The mount is ideal for general applications as well as home-built microscopy systems. It is designed for use with our selection of resolution, distortion, slant edge, and calibration test targets. In addition, it is also compatible with our rectangular microscope slides, filters, dichroic mirrors, variable ND filters, and fluorescence imaging filters.

Two actuators on the side of the mount enable manual positioning over a 50 mm (1.97") x 30 mm (1.18") area. These actuators can be adjusted by hand or with a 5/64" (2 mm) hex key (not included). Each axis of translation is equipped with a vernier scale that provides a resolution of 100 µm, allowing for repeatable positioning of the mounted optic. Each actuator can be locked by a 5/64" (2 mm) hex setscrew. Five 8-32 (M4) tapped holes support six possible mounting orientations when used with our Ø1/2" posts, of which a selection are shown below

Optics are secured with two support arms that each contain two 5/64" (2 mm) hex, nylon-tipped setscrews. Each support arm can slide along a channel in the mount to accommodate different optic sizes; a 5/64” (2 mm) hex setscrew is used to lock each support arm in place. This mounting mechanism can be seen in the photo to the upper right. By loosening the top locking screws, the arms can be removed from the channel and reversed, as shown in the image to the bottom left. When reattaching the arms, simply align each locking screw with one of the 2-56 captive nuts in the channel and tighten. This feature is useful in applications that require the target to be positioned close to a lens or other optical element in a system. 

Please note that the support arms overlap the optic by 4.4 mm on each side.
