CGS Optical Bench

The Compact Grating Spectrometer CGS UV-NIR is an extremely compact, rugged optical bench, configurable with CCD or PDA detectors, allowing users to measure with maximum quality and optimal spectral efficiency.

The CGS is built around an aberration-corrected blazed, flat-field imaging grating, an optical entrance and an uncooled CCD detector or a silicon photodiode array (PDA).

The back-thinned CCD with high QE, has an electric shutter function allowing for very short integration times. The PDA sensor delivers very low noise and large full well, achieving very high dynamic range.

Entrance is SMA with an internal slit, available in different widths. All optical components are mounted in a housing made of aluminum. The spectrometer modules are compact and thermally stable, making them ideal for industrial applications. Their excellent thermal stability and a very low amount of stray light ensure reliable measuring results – even in rough environments.
