Abstract

The Optical Monitor Camera (OMC) is a part of the scientific payload of the INTEGRAL spacecraft, scheduled to be launched in 2001. The OMC is an imager that will monitor star variations in the V-band in a 5 X 5 degree field of view. It is required that the instrument detects object of plus 19.7 magnitude within the FOV. This requires highly sophisticated baffling techniques to provide attenuation up to 10^-45. To obtain such performances, the design of each sub-element is optimized to fulfill very stringent stray-light requirements. The stray-light sources are discussed and performances are simulated with a 3D ray-tracing model.
