Patented, vibration-insensitive measurements at NIR, SWIR, and MWIR wavelengths.
High performance Twyman-Green laser interferometers offer accurate, repeatable measurement for testing optics at infrared wavelengths
PhaseCam Twyman-Green infrared interferometers accurately measure concave, convex and afocal infrared components, as well as infrared telescopes and lens systems. 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.
PhaseCam NIR and SWIR Infrared Interferometers
Small and lightweight, PhaseCam NIR and SWIR systems incorporate patented Dynamic Interferometry® technology to acquire data thousands of times faster than a temporal phase shifting interferometer. Because acquisition time is so short, the systems can be used without vibration isolation in the most challenging environments.
