4D Technology's 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.


Available from Laser Physics, FizCam Fizeau dynamic laser interferometers, from 4D technology provide accurate, large aperture measurements.

PolarCam Micropolariser Camera

4D Technolgy's PolarCam™ snapshot micropolariser cameras capture images of multiple polarised angles from each video frame, enabling a range of image enhancement techniques and polarimetric measurements.

4D Technology AccuFiz Fizeau Laser Interferometer

The compact AccuFiz® Fizeau laser dynamic interferometer offers an unmatched combination of performance, quality and value, for high accuracy shape and transmitted wavefront quality measurements of optical surfaces, components and systems.

4D Technology NanoCam

The NanoCam Sq dynamic optical profiler measures surface roughness on small and large optical quality surfaces. The non-contact NanoCam Sq replaces slow, messy replication methods required with traditional workstation optical profilers.


FlexCam provides high resolution 3D metrology in a highly compact package. FlexCam can be used as an affordable, stand-alone solution for in situ measurement of surface roughness or defects on large optics, such as glass windows or films.

4Sight Wavefront Analysis Software

4Sight analysis software is the most comprehensive platform for accurate wavefront analysis and surface shape measurement. Its smart, straightforward interface puts features and displays where you need them. Stable, glitch-free operation boosts productivity, day after day. 4Sight’s Windows-standard menus and screens make learning 4Sight easy, and put impressive analysis power at your fingertips.
