The PhaseCam® 4020HP dynamic laser interferometer includes a high power, 25 mW HeNe laser for low reflectivity (<1%) measurement setups, such as measuring aspheres using Computer Generated Holograms (CGHs).
The PhaseCam 4020HP incorporates
a single camera, high-speed optical phase sensor that makes
a wavefront measurement in less than 30 microseconds—hundreds
of times faster than a temporal phase shifting interferometer.
Because acquisition time is so short, the PhaseCam can
be used without vibration isolation or turbulence control,
making it ideally suited for use on the production floor,
in clean rooms and in environmental test chambers.
