Request Info4D Technology CorporationTUCSON, Ariz., Oct. 29, 2008 – The FizCam 2000 high performance Fizeau interferometer has been introduced by 4D Technology Corp. to provide accurate measurement of large diameter flat optics. The interferometer features a 12-in. aperture and uses dynamic interferometry to acquire all measurement data in less than 1 ms. It is insensitive to vibration and air turbulence, making it suitable for use in difficult environments without additional isolation. The on-axis design eliminates inherent aberrations, software corrections and alignments typical with tilted beam Fizeau systems, according to the company.
