The FizCam 3000 dynamic laser interferometer is an entirely new Fizeau design, providing highly accurate measurement of optical grade surfaces even in the presence of vibration and air turbulence. Its completely on-axis design eliminates the inherent aberrations, software corrections and painstaking calibrations and alignments typical of tilted beam Fizeau systems. The result is remarkable measurement quality and ease of setup.
The FizCam 3000 incorporates patented Dynamic Interferometry® technology using a single camera, high-speed optical phase sensor that makes a wavefront measurement in less than 1 millisecond. Because acquisition time is so short, the FizCam 3000 can be used under almost any conditions, even for measuring moving parts, without vibration isolation. Look-down and side-mounting options are available.
“Turbulence in our test lab was causing data drop-out as well as degrading our measurement repeatability while performing double-pass, long path-length measurements of our telescope systems. We installed the FizCam 3000 to mitigate these effects and immediately improved our data repeatability by 2X and reduced our data drop-out to zero.” Tim Goodman, Optical Engineer, L-3 Communications Sonoma EO.
