Large wavefront phase errors introduced by small thickness changes in multilayer high reflectance coatings are discussed. The importance of measuring these wavefront phase errors at the wavelength the coating is to be used is illustrated. Plans for an interferometer working at a wavelength of 3.8 microns for measuring wavefront phase errors introduced by coating nonuniformity are described.
