The LightHUB(R) Compact Laser Combiner can be equipped with up to four DPSS or diode lasers of different wavelengths in a compact and rugged design. Wavelengths between 375nm and 830nm and optical output powers up to 150mW per laser line are possible. The Compact Laser Combiners can be equipped with polarisation maintaining fibre coupling units to supply the light to applications in biotechnology like confocal microscopy and flow cytometry.
