Abstract
Process and apparatus for automated production of optical devices comprising two plane parallel optical surfaces of a desired optical performance for transmitted light, by measuring and quantifying the spectral response of intensity versus wavelength across the working surface area of a starter optical device as compared to an acceptable computer model, as a three dimensional contour map of optical thickness based on the assumption of a constant index of refraction, then reducing the high spots by automated means such as polishing, and measuring the spectral response again.
