Phasecam Twyman-green Laser interferometers
PhaseCam dynamic Twyman-Green laser interferometers provide high resolution measurements despite vibration and air turbulence. Dynamic Interferometry® enables PhaseCam laser interferometers to capture full wavefront measurements in as little as 30 microseconds—5000 times faster than conventional phase shifting interferometers. Compact and lightweight, PhaseCams make reconfiguring test setups simple and easy, without vibration isolation.
Twyman-Green laser interferometers offer several important advantages over more traditional Fizeau instruments:
Vibration-insensitive measurement enables use in challenging environments such as cryo-vac testing or over long measurement paths.
The design can be extremely compact, enabling use in tight spaces, or in difficult-to-access locations.
The on-axis design provides excellent accuracy, particularly when measuring spherical elements.
The ratio between the test and reference beams is adjustable without loss of power
