OBIS LG and XT

OBIS LG and OBIS XT products are moving the self-contained OBIS concept into the UV and into a powerful visible wavelength, which are ideal for the latest UV fluorochromes and established 640nm excitable fluorochromes.

Low-noise UV and VIS lasers are ideal for OEM instrumentation applications in flow cytometry, super-resolution microscopy, confocal microscopy, and semiconductor inspection. Control electronics are integrated within the laser head. OBIS XT models generate very low thermal load.
