Abstract

In practice, form deviations of technical surfaces lie within the micro- and submicrometer range. They often exhibit a micro structure of over 100 cycles/mm. Thus an interference microscope with an interference increment within the micrometer range is required for measuring the micro structure. An object field of 5 mm x 5 mm is usually necessary for a complete examination. Prism inferometry offers a favourable and practicable solution.
