FizCam dynamic Fizeau interferometers provide accurate, large aperture measurements even in challenging environments. FizCam systems capture full wavefront measurements in under 1 millisecond, enabling accurate measurement even in the presence of vibration and air turbulence. Their on-axis design eliminates the aberrations, software corrections and painstaking calibrations typically required with tilted beam Fizeau systems.

FizCam laser interferometers excel at general optics and large (meter-class) optical component testing. as well as analysis of moving parts. FizCam systems are equally at home in the lab or in noisy environments such as production floors and clean rooms. Short and long coherence length options enable difficult measurements such as remote cavities, simultaneous measurement of multiple glass surfaces, or measurements in environmental testing chambers.

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

FizCam 2000 Short coherence for general optics, double-sided glass, remote cavities, environmental chambers and more

FizCam 3000 Long coherence for general optics, large optics, long cavites and moving parts

Remote Cavity Measurements

For Fizeau measurements, the "cavity" is the space between the test and reference surfaces. Most phase-shifting Fizeau interferometers require that the reference flat be mechanically translated to acquire the phase data, which usually requires the reference to be physically attached to the interferometer.

4D's FizCam 2000, which employs patented Dynamic Interferometry, does not require the reference to be mechanically translated, so no moving parts or ...
