Designing Large Fizeau Interferometers
Laser Fizeau interferometers are the workhorses of optical testing. With proper configurations and accessories, these instruments enable characterization of flats, prisms, concave and convex lenses, and even aspheric elements. While many laser Fizeau systems produce output beams that are 6 in. or less in diameter, the increased production of telescopes, satellites, high-power lasers, and other novel optical systems are driving a greater need for systems with output apertures larger than 12
