What's Your Spectral Challenge?

Aug 26, 2025 by IDEX Health & Science

To overcome the obstacles many fluorescence instrument designers and users face with spectral management, our experts created SearchLight^™.

• Can’t find the right fluorophore?
• Struggling with filter selection?
• Don't have time to set up custom models?

We have a solution to these spectral challenges (and more).

Take the guesswork out of spectral selection and hello to SearchLight, our free and intuitive online plotting tool. SearchLight empowers you to visualize, optimize, and validate your optical system, ensuring your design works—before you even order a part.

Let’s explore some common examples:

Challenge: I can't find the right fluorophore.
Solution: Explore 800+ fluorophores with instant spectral plotting in SearchLight.

SearchLight contains an extensive library of over 800+ fluorophores, 150+ light sources, more than a dozen detectors, and Semrock’s entire library of filters and filter sets.

 

Challenge: I struggle with Filter Selection.
Solution: Match your light source and detector perfectly with the full Semrock filter catalog inside SearchLight.

SearchLight’s intuitive user interface makes it easy to manipulate component specifications and plot spectral results that allow users to make smarter decisions without wasting time and money.

 

Challenge: How Do I Know My System Will Work?
Solution: Use our SearchLight spectral visualization tools to model and optimize performance before your build.

Any number of spectra may be plotted simultaneously, and an entire graphing session sent to colleagues for collaboration using the “Share” feature. SearchLight sessions can also be saved into your personal account for future use.

 

Challenge: I Don't Have Time to Set Up Custom Models.
Solution: Skip the setup by jumping into pre-configured spectral models within SearchLight.

• Evaluate and optimize your system configurations
• Save, Share, & Export your results for better collaboration
• Take advantage of the regularly updated databases
• Save time in the lab and make every photon count with SearchLight
