Revolutionary innovations are rare. In the field of optical test interferometry, the HeNe laser revolutionized its application and use; now, SCI promises to do the same.
How good is your interferometer? Has system performance degraded since last year? How does one system compare to another? Do annual "calibrations" provide the complete picture...
A large-aperture, low-uncertainty laser Fizeau interferometer with highly expanded dynamic range enables accurate qualification of high-performance aspheric optics.
