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 of power between test and reference is adjusted in a lossless fashion

PhaseCam 6000 Laser Interferometers
With a tiny, easy-to-position, fiber-coupled measurement head and motorized controls, the PhaseCam 6000 is ideal for on-machine metrology, remote mounting in measurement towers or pressure vessels, and other challenging environments. PhaseCam 6000 is a Twyman-Green interferometer.
PhaseCam 4020 Laser Interferometers
The PhaseCam 4020 features simple, manual controls and vibration immunity. Flexible and low cost for the lab or shop floor.
PhaseCam NIR Laser Interferometers
Lightweight and vibration-insensitive for surface and wavefront measurements at near infrared (1.053, 1.064, 1.3 and 1.55 micron) wavelengths.
PhaseCam SWIR Laser Interferometers
Compact, lightweight and vibration-insensitive for accurate surface and wavefront measurements at 1.55 micron wavelengths.
PhaseCam IR Laser Interferometers
Accurate surface and wavefront measurements at 3.39 micron wavelength. These dual mode systems operate in vibration-immune mode for demanding environments such as clean rooms, or in traditional, temporal phase-shifting. Ideal for quality verification of IR optics, focal optical systems and afocal components.
PhaseCam 4020HP High Power Laser Interferometers
A high power, 25 mW HeNe laser makes it possible to measure low reflectivity (<1%) setups, such as measuring aspheres using Computer Generated Holograms (CGHs).
