Abstract

This paper describes the design and performance of a brassboard astrometric beam combiner. The beam combiner was developed as part of the JPL Interferometry Technology Program . The purpose of this program is to test out design concepts in hardware that will eventually be used for the Space Interferometry Mission. The label brassboard implies that the beam combiner is flight-like in terms of fit and function. The beam combiner met its design performance except for fringe visibility. Although it has not been environmentally tested as an assembly, the beam combiner was designed to survive the appropriate thermal and vibration tests.
