Fizeau Interferometer
TUCSON, Ariz., May 15, 2024 — The AccuFiz® Duo from 4D Technology is a dual source dynamic laser Fizeau interferometer for measuring flats and lenses without the need for coating surfaces to attenuate extraneous interference fringes. This is due to a short coherence mode that enables surface error, transmitted wavefront error, remote cavity, wedge, optical thickness, and homogeneity measurements of plane parallel transparent surfaces down to 0.2 mm thick. The AccuFiz Duo also includes a long coherence source that uses a...
