MORE ABOUT 4D

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.

4D PhaseCam 4020 dynamic Twyman-Green interferometer enables vibration-insensitive measurement of large concave telescope mirrors, complex lens systems, and afocal components such as flat mirrors and collimators
