Interferometers Characterization

Procedure and characterization result for two vibration insensitive phase shifting interferometers will be presented. Typical applications of the vibration insensitive interferometers include the testing of large astronomical primary mirrors with long radii of curvature in a severe vibration environment. The procedure list the steps for characterizing the two interferometers. The characterization compares the two interferometers and compares to its own specification.

Cryogenic Optical Testing at the Marshall Space Flight Center

Optical test results of several lightweight mirrors using different instruments will be presented. Several optical figure-testing techniques were used to overcome the vibration problem associated with optical testing with long optical path length.
