Phasicswavefront sensor

The SID4 wavefront detector developed by French company Phasics using innovative technology has the following technological advantages:

◆high resolutionThe phase map has the highest resolution possible400ｘ300.

◆ Havingdirect measurementThe ability of highly divergent light beams

◆achromatic, MatchCCDThe entire detection range is used for different wavelengths of light without the need for additional calibration.
