Our Intellium™ Asphere Fizeau Interferometer measures aspheric optics at record speeds, by utilizing sub-Nyquist technology. This allows approximately 2000 fringes to be processed using common resolution cameras. In addition, our IntelliWave™ Software performs retrace error removal due to the use of spherical reference optics.
