Centration of optical elements

Ezra Milby, Jim Burge

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Axisymmetric optical components such as lenses are frequently centered with the use of rotary air bearings, guided by optical instrumentation that use reflected or transmitted light. This report systematically explores methods of adjusting optical elements including wedged-shims, fine pitch screws, and positioning rods with a goal of defining the accuracy that can be expected. Analysis of the performance is supported with experimental data. A characterization and discussion of the merits of each positioning method is additionally presented.
