Ultra-Stable Fluorescence Light Source for Microscopy
The X-CitešExacte ultra-stable fluorescence light source employs a DC-powered mercury lamp coupled with proprietary Closed-Loop Feedback technology to provide unmatched short and long-term intensity stability, for imaging protocols lasting from milliseconds to days. With the X-Cite Optical Power Measurement System, light output can also be calibrated in absolute power units (watts), ensuring truly repeatable fluorescence illumination for imaging experiments.
The X-Cite Exacte microscope light source has the convenience of pre-aligned, long-life lamps and easy installation combined with innovative functions in the newest generation of mercury arc fluorescence illumination systems.
