Near-infrared SC (supercontinuum) light source

Hamamatsu’s near-infrared SC light source is a compact laser light source with a broad spectrum and laser characteristics such as high coherence and brightness.
It uses a broad spectrum laser that is generated by non-linear optical phenomenon with an ultrashort pulsed laser.
