MIRI telescope simulator (MTS) folding mirrors
Abstract
The MTS Folding Mirror Subsystem is part of the MIRI Telescope Simulator, which is an Optical Ground Support Equipment for ESA MIRI (Medium Infrared Instrument) Qualification, in the frame of the James Webb Space Telescope Program. The program prime contractor is INTA (Spanish National Aerospace Centre). The Subsystem consists of four different mirrors assemblies to adapt the optical path to the available envelope; the mirrors are placed between exit pupil and image plane with suitable orientation to reproduce specific chief ray deviation. Remote adjustment for image compensation at cryogenic conditions is available for two mirror assemblies, by means of two independent rotation mechanisms. A manual tip-tilt system is also provided for system adjusting at ambient conditions in all four mirror assemblies.
