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
