Steimle, Lawrence J.; Wang, Yaujen, 1993, "Development of a Broadband Achromatic Twyman-Green Interferometer", https://hdl.handle.net/2014/36640, UNKNOWN, JPL Open Repository
A modified Twyman-Green interferometer is in use that makes possible wavefront testing of optical filters at any wavelength from 200 to 1100 nanometers. The use of mirrors for collimation and pupil imaging makes the intrument achromatic, and therefore the focus is fixed over the... |
