Thorlabs offers a selection of Fluorescent Microscope Slides and Alignment Targets for use with widefield, confocal, or multiphoton fluorescence imaging systems. Manufactured from a cast acrylic substrate, they are available in five different colors: blue, green, yellow, orange, and red. Each color has a fluorescence spectrum similar to a variety of fluorophores; see the Fluorescence Graphs tab for more details. These slides, disks, and plates provide a continuous fluorescent field so that field of view, illumination consistency, and sample alignment may be assessed and adjusted prior to using a sample containing a fluorophore.
The fluorescent microscope slides are compatible with our sample holders that fit 26 mm x 76 mm, 1.7 ± 0.5 mm thick slides. Each slide is available individually, in packs of five, or in a slide set that includes one slide of each color. The fluorescent alignment disks can be mounted using our Ø1" fixed optic mounts, lens tubes, or 30 mm cage plates. Each disk is available individually or in packs of five. The fluorescent cage alignment plates are engraved with concentric circles and have a central through hole aligned with the center of Thorlabs' cage systems. These drop in alignment tools are available individually for 16 mm, 30 mm, and 60 mm cage systems.
For custom color, sizes, and shapes up to 1' x 2', please contact Tech Support.

This is from Adiuvo Diagnostics Pvt Ltd, a Chennai-based medical device startup.
We are interested in the fluorescent microscope slides in Thorlabs's product line. However, could you please clarify if the fluorescence in these samples can be excited across a range of UV wavelengths. We are interested in testing specifically at wavelengths 365 nm, 395 nm, and 415 nm. cdolbashian
(posted 2024-03-13 04:34:13.0) Thank you for reaching out to us with this inquiry. We plot the fluorescence responsivity data which we have for these slides within the 'Fluorescence Graphs' tab above. For some of these wavelengths which you have provided, I see we have some test data, though not for all of them. I have contacted you directly regarding the compatibility of these slides with your experimental endeavors. Santhosh Mamidala
(posted 2023-09-11 10:40:46.357) I am looking for calibration slides for Nikon Ti2-E widefield microscope to measure fluorescence intensity. Does this FSK5 set can be used for this purpose to measure in DAPI/TRITC/FITC/Cy5? ksosnowski
(posted 2023-09-12 10:10:04.0) Hello Santhosh, thanks for reaching out to Thorlabs. Unfortunately, we do not batch-test these and we do not control for a specific tolerance of the fluorescence response of these slides. These are not intended for use as a spectral calibration reference but are rather for field of view, illumination consistency, and sample alignment assessment. The exact spectra varies between different physical units however which presents issues if used as a reference in this manner. Andrea Nardi
(posted 2023-08-30 08:04:13.33) Do you have any absorption spectrum of the slides? cdolbashian
(posted 2023-08-30 09:16:34.0) Thank you for reaching out to us with this inquiry! Unfortunately, all the data we have regarding these acrylic slides is presented on the various tabs above. We have not, at the time of posting, characterized full absorption spectra for each of these products. user
(posted 2023-08-04 11:25:06.127) Hello, I was wondering if you have spectra of the quantum efficiency of the slides? cdolbashian
(posted 2023-08-04 12:18:35.0) Thank you for reaching out to us with this inquiry. All of the data we have regarding these test targets are presented on the overview and graphs tabs of this web presentation. Yuri Sacha Correa Lopes da Silva
(posted 2023-06-07 14:40:46.55) Could you guys make a version of that product to 1550nm? It would be very useful to use two to align the cavities I use. cdolbashian
(posted 2023-06-21 11:07:17.0) Thank you for reaching out to us with this inquiry! We actually do make IR alignment tools, which can be found here:https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=3201
I have contacted you directly to discuss your particular application. Arjan Tibbe
(posted 2023-03-10 10:43:40.417) The fluorescence spectra listed on the website of the fluorescent microscope slides are not correct. Can you provide the real fluorescence spectra?
Thanks jgreschler
(posted 2023-03-16 04:38:25.0) Thank you for reaching out to Thorlabs. Some part-to-part variation is to be expected with these products, the graphs provided are examples of previously tested items in the product line. I've reached out to you directly to review the data you collected and discuss whether or not it falls within the normal operating bounds for this product. If it does not we can issue you a tested replacement. Alex Adams
(posted 2022-11-07 13:41:40.993) Dear support, What are the fluorescence lifetime's of each slides ? Thanks, Alex cdolbashian
(posted 2022-11-08 01:32:45.0) Thank you for reaching out to us Alex, unfortunately these particular targets are intended for qualitative measurements and alignment purposes. While we tolerance their dimensional properties tightly, we do not have lifetime data for this fluorescent acrylic. All performance data we have is on the product page and different "graph" tabs. Antonio Yu
(posted 2022-01-09 20:46:19.863) Dear support,
Could you please provide the life time of each slides ? Thanks.
BR,

(posted 2022-01-11 11:06:05.0) Thank you for reaching out to Thorlabs. Additional specifications can be requested by contacting Technical Support. I have reached out to you directly to discuss this topic further. Lothar Schmid
(posted 2021-06-30 09:50:51.8) Hi Thorlabs team,
I have a few questions regarding the fluorescent microscope slides, which I would like to use for intensity calibration of a fluorescent reader:
* How reproducible is the fluorescence intensity from batch to batch?
* Do the spectra change over time?
* Do the slides show bleaching of fluorophores?
* Is the fluorescence temperature-dependent, for a temperature range between 0 and 60 degC?
Thanks,
Lothar Schmid cdolbashian
(posted 2021-07-20 08:28:30.0) Thank you for your interest in Thorlabs products. These materials are, unfortunately, not characterized in this manner. All data we have for them is provided on the web page. I have reached out to your to discuss your application directly. Gary Riggott
(posted 2021-02-17 12:53:43.627) Hi-
The results I've gotten with my fluorimeter do not match your reference spectra very well and I'm wondering if you have any thoughts on this.
Blue Std:
My result shows a broad peak from about 400 to 480nm that doesn't exist in the spectrum for the standard.
Green Std:
I get a broad peak from 480 to about 560nm with a max at 501. The reference shows a well-defined big peak at 499nm.
Orange Std:
I get a broad peak from about 580 to 610 with a max at 587. The reference shows a minor peak at 612, and I don't have anything there.
Yellow Std:
My only peak is at 366nm. The reference shows a major peak at 493 and a minor peak at 517. This is the worst agreement between measured and expected among any of the standards.
Red Std:
I get a peak at 566 and a broad peak from about 580-630, with a max at 598. The reference shows peaks at 472, a big one at 586 and a broad peak from 620-625. I have no peaks near 472nm.
I welcome any input.
If you could add a second "Run" or spectrum as you did with the %Transmission curves, that would be a huge help!
Thank you,
Gary YLohia
(posted 2021-04-14 02:36:20.0) Hello Gary, thank you for contacting Thorlabs. After going over the data you sent us and talking to our team here, it seems like the discrepancy that you are seeing ranges from 3 - 10 nm, which can be attributed to a lot-to-lot variation. These are not intended for use as a calibration spectra but are rather for field of view, illumination consistency, and sample alignment assessment. Vincent Khau
(posted 2020-12-01 18:18:29.887) Do you have data on the fluorescence variation from batch to batch for the blue fluorescence slide? Is there a certain tolerance that these slides are manfuactured to in terms of their fluorescence response?
Thank you. YLohia
(posted 2020-12-15 02:49:19.0) Hello, thank you for contacting Thorlabs. Unfortunately, we do not batch-test these and we do not control for a specific tolerance of the fluorescence response of these slides. Dmitry Gorbachev
(posted 2020-02-21 03:38:27.007) Hello! I work with Frequency-Domain FLIM, and I used your fluorescent slides kit FSK5 to tune our FLIM camera. I want to know if it is possible to order the same set of slides from you, but larger? for example 10cm in diameter. Thanks a lot! llamb
(posted 2020-02-25 02:12:46.0) Thank you for contacting Thorlabs. Yes, custom fluorescence slides are indeed feasible. We will reach out to you directly to quote this. Nikola Krstajic
(posted 2019-07-12 09:39:00.04) I work in near-infrared and fluorescence targets geared for ICG exc/emission (785nm exc) would really help me and all colleagues working in this are. I am 100% sure you would sell many. It is also not clear if your fluorescence targets work on 625nm excitation as your spectra show wavelengths below exc and this is really unusual (antistokes is an exception in fluorescence). Thanks a lot! YLohia
(posted 2019-07-23 09:46:29.0) Hello, thank you for your feedback. I have posted your request on our internal engineering forum for further consideration as a future product. petur.hermannsson
(posted 2019-01-21 10:33:44.437) Do you have numbers on the batch-to-batch consistency/uniformity of these slides, as well as the rate of photobleaching? YLohia
(posted 2019-01-28 11:03:57.0) Hello, thank you for contacting Thorlabs. We have actually just updated our web presentation to include some information on the consistency between two runs, and this information can be found in the "Transmission Graphs" tab. That being said, unfortunately, we do not have information on the photobleaching at the moment. |
