2003 Photonics Circle of Excellence Winner

The PhaseCam 4020 is compact and very lightweight, with simple, manual controls for testing focal optical systems such as large concave telescope mirrors and lens systems, and for multi-segment mirror alignment. It can also be adapted for testing small aperture afocal components such as flat mirrors and collimators. A stabilized HeNe laser (632.8 nm) provides excellent stability, while the high speed, 1K x 1K phase sensor makes it is easy to measure moving or complex components, even in challenging environments. Numerous accessories and options are available including different operating wavelengths and a 4 mega-pixel phase sensor.

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
