PhaseCam Twyman-Green Laser Interferometers
Description
Twyman-Green configuration 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 of power between test and reference is adjusted in a lossless fashion
PhaseCam dynamic Twyman-Green laser interferometers provide high resolution measurements despite vibration and air turbulence. Dynamic Interferometry® enables PhaseCams 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.
The PhaseCam laser interferometer is perfect for metrology of large diameter optical components, production floor quality control, clean room applications typically hampered by air flow turbulence, environmental chambers where remote operation is essential, and modal analysis of moving parts, such as deformable mirrors, spinning disks, or vibrating membranes.
