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.
Features
1) High stability: 0.1 % (typical)
2) High brightness: 20,000 times (compared to halogen lamp)
3) Broad spectrum: 1300 nm to 2000 nm
Applications
1) OCT (optical coherence tomography)
2) FT-NIR (Fourier transform near-infrared spectroscopy)
3) Gas measurement
4) Semiconductor wafer inspection
5) Near-infrared spectrophotometry
