Abstract

Modern opticians are finding that yesterday's state-of-the-art design requirements are quickly becoming commonplace and are generating surface figure tolerances of X/8 to A/20 or approximately one to two millionths of an inch. Here it becomes apparent that the classical test plate must give way to a more quantitative method of surface measurement; one that will give the optician a more accurate idea of the true surface geometry which is being polished. A digital minicomputer used in conjunction with a Twyman-Green interferometer is being used as an in-process production tool yielding favorable results.
