Welcome to SearchLight™
The Premier Fluorescence Spectrum and Modeling Resource for Microscopists and Optical System Designers
Start using SearchLight now!
SearchLight is a free, online spectrum plotting and analysis tool that allows fluorescence
microscope users and optical instrument designers to model & evaluate the spectral
performance of fluorophores, filter sets, light sources, and detectors as components
of an overall system. Its intuitive user interface makes it easy to manipulate spectral
component specifications and plot spectral results. The System Calculator allows
the user to quantify system metrics including signal, SNR, and bleed through; as
well as to compare various system configurations against each other.
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.
SearchLight contains an extensive library of 779
fluorescence spectrum models, 140 light sources,
more than a dozen detectors, and Semrock's entire library of filters and filter sets.
"MyData" allows you to upload your own custom datasets for any components not currently
included as a selection choice.
- 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!

Compare System Calculator
SearchLight Compare System Calculator feature quantitatively computes the fluorescence
signal, noise, and signal-to-noise ratio for unlimited combinations of filter sets,
fluorophores, light sources, and detectors. Calculations are based on a straightforward
mathematical framework, which is described in detail in the white paper
Spectral Modeling in Fluorescence Microscopy.
