Abstract

"Tweaking" is a time-honored art in the production of lenses. In recent years it has taken on the more sophisticated name of "Computer-Aided-Alignment". The skilled interpretation of a star image has given way to a phase-modulated Interferometer communicating with an Optical Design Program which calculates "tweaks" of certain elements within the lens - the so-called compensators.
