The X-Cite® 120PC Q offers the same performance and convenience as the X-Cite 120Q fluorescence illumination system - rich spectral sample excitation with a uniformly illuminated field of view, the convenience of pre-aligned lamps, 2000 hour lamp lifetime, and adjustable iris - with the added option and benefits of a computer controlled microscope light source. The straightforward RS-232 communication and command set easily allows integration into automated systems as well as commercially available imaging software platforms.
