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? 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. Challenge: I struggle with Filter Selection. Solution: Match your light source and detector perfectly with the full Semrock filter catalog inside SearchLight. Solution: Use our SearchLight spectral visualization tools to model and optimize performance before your build. Challenge: I Don't Have Time to Set Up Custom Models. Solution: Skip the setup by jumping into pre-configured spectral models within SearchLight.
