Features

  • Assess and Align Fluorescence Imaging Systems
  • Five Different Fluorescence Spectra Similar to a Variety of Fluorophores (See the Fluorescence Graphs Tab) 
  • 25.4 mm x 76.2 mm, 1.7 mm Thick Fluorescent Slides
  • Ø1", 1.7 mm Thick Fluorescent Disks with Engraved Target or Hole in Disk Center
  • 1.7 mm Thick Orange Fluorescent Cage Alignment Plates for 16 mm, 30 mm, and 60 mm Cage Systems

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 mountslens 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.

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!

Thank you for contacting Thorlabs. Yes, custom fluorescence slides are indeed feasible. We will reach out to you directly to quote this.

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!

Hello, thank you for your feedback. I have posted your request on our internal engineering forum for further consideration as a future product.

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.

Fluorescent Alignment Plates

fluorescing alignment plate
Click to Enlarge

CPA3 Alignment Plate in a
30 mm Cage System
  • Orange Fluorescing Cast Acrylic Plates for 16 mm, 30 mm, and 60 mm Cage Systems
  • Guide Lines and Ø1 mm or Ø5 mm Through Hole Aligned at Center of Compatible Cage System
  • Quick, Drop-In Alignment Tools for Fluorescence Imaging Systems

These drop-in alignment plates are convenient tools for spatial calibration and alignment of cage-based fluorescence imaging systems. The cast acrylic substrate produces fluorescence spectra similar to orange fluorescing proteins and dyes. These plates provide a continuous fluorescent field so that the field of view, illumination consistency, and sample alignment may be assessed and adjusted prior to using a sample containing a fluorophore.

Each plate is cut from cast acrylic material with a thickness of 1.7 mm and has either a Ø1 mm or Ø5 mm through hole aligned at the center of the cage assembly. Each through hole is surrounded by concentric, engraved alignment rings. Options are available for compatibility with our 16 mm, 30 mm, and 60 mm cage systems. For custom colors and sizes up to 1' x 2', please contact Tech Support.
