PhaseCam Twyman-Green Interferometers

PhaseCam dynamic Twyman-Green interferometers provide high resolution measurements that are insensitive to vibration and air turbulence. PhaseCams 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 isolation equipment or air turbulence abatement.

The PhaseCam laser interferometer is perfect for metrology of large (meter-class) 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.

PhaseCam laser interferometers are sold as turnkey systems, including installation, training, the latest computer hardware, and industry-leading 4Sight data analysis and visualization software.

Deformation of Diffuse Surfaces

PhaseCam technology has been incorporated into a number of unique configurations for application-specific measurements. The SpeckleCam (Electronic Speckle Pattern Interferometer) can measure large, diffuse, precision surfaces up to 30 times per second, detecting minute changes in response to environmental changes. Instantaneous data acquisition, vibration insensitivity, high precision and high spatial sampling allow the ESPI to excel in noisy environments such as cryogenic test chambers. These ...
