Abstract

Research Optics & Development, Inc. is using a slope tracing profilometer to measure the figure of optical surfaces which cannot be measured conveniently by interferometric means. As a metrological tool, the technique has its greatest advantage as an in-process easurement system. An optician can easily convert from polishing to measurement in less than a minute of time. This rapid feedback allows figure correction with minimal wasted effort and setup time. The present configuration of the slope scanner provides resolutions to 1 micro-radian. By implementing minor modifications, the resolution could be improved by an order of magnitude.
