Paper Abstract
The Astrometric Beam Combiner (ABC) is a critical element of the Space Interferometry Mission (SIM) that
performs three key functions: coherently combine starlight from two siderostats; individually detect starlight for
angle tracking; and disperse and detect the interferometric fringes. In addition, the ABC contains: a stimulus,
cornercubes and shutters for in-orbit calibration; several tip/tilt mirror mechanisms for in-orbit alignment; and
internal metrology beam launcher for pathlength monitoring. The detailed design of the brassboard ABC (which
has the form, fit and function of the flight unit) is complete, procurement of long-lead items is underway, and
assembly and testing is expected to be completed in Spring 2009. In this paper, we present the key requirements
for the ABC, details of the completed optical and mechanical design as well as plans for assembly and alignment.
