Deep ultraviolet lasers for flow cytometry [PDF]
Cytometry Part A, 2018 AbstractModern flow cytometers require multiple laser wavelengths to excite the wide variety of fluorescent probes now available for high‐dimensional analysis. Ultraviolet (UV) lasers (typically solid state 355 nm) have become a critical excitation source for the Brilliant Ultraviolet (BUV) series of polymer fluorochromes.
