Abstract
A new process at Xerox Electro-Optical Systems, which stems from an interferometer equipped with a cylindrical transmission lens, is the ability to in-process test cylinders on-the-block. This capability permits evaluation of the surface at the most economical point, while preserving the capability to correct same. Furthermore, expensive cylindrical test plates, which can each run hundreds or thousands of dollars, can be eliminated. In addition, startup time or change time is reduced, since the potentially long wait for fabrication of cylindrical test plates is eliminated.
