Abstract


A study on the calibration of Fizeau interferometer in order to obtain its accreditation as a flatness measuring instrument is presented. The interferometer will be used for measuring and calibrating optical flats with a maximum aperture diameter of 15 cm. It is shown here that the uncertainty contribution due to both, the interferometer and the measuring method employed is small as compared to the optical flats used in the calibration procedure.

Keywords
