Microscopy Illumination Sources

Our LEDs and liquid light guides are ideal for epi-fluorescence imaging. Our wide selection includes excitation wavelengths ideally matched to AlexaFluor dyes, DAPI, and other common fluorophores, as well as options for the newest fluorescent proteins that emit in the near-IR (700 nm and beyond). For microscopy applications, Thorlabs has designed specialty light sources. These include collimated LEDs, multi-wavelength LED sources, and broadband lamp-based light sources.
