Optronic Laboratories, located in Orlando, Fla., has delivered a specially designed version of its popular OL 490 agile light source to the National Institute of Standards and Technology (NIST) in Gaithersburg, Md. NIST commissioned the custom OL 490 for a range of specialized applications ranging from hyperspectral imaging of human hepatic cells and tissues undergoing various stimuli to imaging endogenous fluorescence from live corals. The device will be used to study how to stretch the contrast between similarly colored, but functionally different, features in tissues through variation of the spectral distribution.
