Handbook of Optical Testing Methods for Diamond-Turned Mirrors. Volume 2

摘要

The information in this report should be most useful to technical testing large metal mirrors and to the manufacturing engineers who have the responsibility for diamond turning high-quality optical components. The effects of lenses in forming and altering wavefronts are discussed so that the tester will be aware of all the circumstances responsible for generating an interferogram. Both visual and computer interpretation of the interferogram are discussed, with emphasis on the necessity for proper understanding of the test so that the computer result will be accurate. The axicon is an optical shape which is unfamiliar to most testers. Special considerations for testing and evaluating the errors of this element are described.
