PhaseCam Twyman-Green Infrared Interferometers
Compact, lightweight and vibration-insensitive for NIR, SWIR, MWIR and IR measurements.
High performance, quality and value, for accurate, repeatable measurement of surface shape and transmitted wavefront quality.

Measure infrared optics and systems at 1.053—3.39 micron wavelengths
PhaseCam Infrared Interferometers
PhaseCam Twyman-Green infrared interferometers accurately measure concave, convex and afocal infrared components, as well as infrared telescopes and lens systems.
PhaseCams incorporate Dynamic Interferometry® technology, using a single camera, high-speed optical phase sensor to acquire data thousands of times faster than a temporal phase shifting interferometer. Because acquisition time is so short, a PhaseCam IR interferometer can be used without vibration isolation in the most challenging environments.
Ultra-small and lightweight, with a fiber-coupled measurement head, a PhaseCam IR interferometer is incredibly easy to mount and position. PhaseCam systems are ideally suited for measuring infrared optics over long paths, for remote mounting in measurement towers or pressure vessels, and for other challenging test setups. Optional Dynamic mode lets you measure despite vibration and air turbulence, without an air table.
