Beam Quality Measurement from 400-1750 nm
The CinSquare InGaAs system is a fully automated instrument to measure NIR beam quality of CW and/or pulsed laser systems from the 400 to 1750 nm spectral range. The system consists of a fixed focusing lens in front of a motorized translation stage carrying the camera-based InGaAs beam profiler. Its operational robustness and reliability ensures continuous use applications in industry, science, research and development.
The sensor window is removed, thus avoiding any fringing/interference artifacts in the measurements.
According to ISO 11146-1/2 the CinSquare system measures the complete beam caustic and determines M², waist position, divergence, etc., related to the reference plane. To facilitate its use, the CinSquare InGaAs system is equipped with two alignment mirrors for exact positioning of the laser beam and a filter wheel for incremental beam attenuation.
