Correction of parabolic errors in fabry-perot interferometers.
Methods are described for correcting parabolic errors in Fabry-Perot interferometers using evaporated films and an appropriate shutter. Errors of lambda/50 can be readily reduced to less than lambda/400 over 54-mm apertures (lambda approximately 550 nm).
