Optical Metrology

High quality optics manufacture requires high precision measurement solutions  and 4D Technology's Dynamic Interferometry systems and Wavefront Analysis Software provides state-of-the-art solutions for demanding metrology applications in the lab or production environments - even in the presence of vibration and turbulence.

4D interferometers and optical profilometers are used daily for critical measurement applications in astronomy, aerospace, optical testing and many other industries.

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.


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.


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.


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.

4D Inspec Surface Guage

The 4D InSpec Surface Gauge is the first handheld, precision instrument for non-contact measurement of surface features and defects. With micrometer-level resolution, portability, affordability and ease-of-use, the 4D InSpec puts high resolution measurement on the factory floor, in machine shops and in field service applications.

4Sight 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.
