Paper Abstract

We will report on a new interferometer developed at Carl Zeiss, which has real-time measuring capability with instant visualization of results, is nearly insensitive to vibrations, has a variable fringe spacing from one lambda to lambda/1O (lambda represents the wavelength of the light used in the interferometric test), and can give lambda/100 accuracy through a simple calibration procedure. It can be handled with the same ease and in just the same way as conventional interferometers.
