US Patent:
4406543, Sep 27, 1983
Filed:
Jul 17, 1981
Appl. No.:
6/284366
Inventors:
Michael H. Nemiroff - Del Mar CA
Chris C. Bowman - Pittsburgh PA

Assignee:
Burroughs Corporation - Detroit MI
International Classification:
G01B 1114, G01B 1130
US Classification:

Abstract:
Disclosed is an interferometer having an optical flat having a coated reference surface of aluminum whose thickness is in the range of 100-500 A (preferably about 300 A) covered with a coating of silicon dioxide of a thickness in the range of 1,000-10,000 A (preferably about 3,000 A). Such a coating on an optical flat when in engagement with a surface of an object to be tested greatly enhances the contrast of the interference fringes.
