Vacuum Compatible
Patented vibration-immume interferometer for vacuum and thermal testing
The small PhaseCam is mounted in a pressure vessel, enabling remotely-operated testing of optics inside environmental and cryovac chambers.
The PhaseCam® Twyman-Green system provides accurate, quantitative measurement of surface shape, even in the presence of vibration or air turbulence. The vacuum-compatible PhaseCam includes fully automated controls, enabling mounting in remote locations. The stainless steel case enables the PhaseCam to be operated within a vacuum chamber.

The PhaseCam’s patented optical configuration and 4MP camera permit high-resolution, interferometric measurement of optical phase in as little as 30 microseconds. Such high speed makes it possible to measure with the significant vibration often found in environmental chambers. A range of diverging lenses provide versatility for positioning the instrument in your measurement path.
The compact system installs easily, with nitrogen-based cooling and a single 2-cable tether providing all electronics connections.
Vibration insensitive
30 microsecond data acquisition time—measure despite pump noise and vibration
Test setup flexibility
Easy positioning within the test path—and inside the pressure vessel/test chamber
Accessory optics
A wide range of diverging lenses further simplifies the test setup
