Paper Abstract

A novel design for a chopping infrared secondary mirror using silicon carbide has been proposed which is compatible with a 0.1 arcsecond image quality, 8 meter class telescope. The image quality response to inputs such as changing gravity orientation, wind loading, thermal loading, active correction tilt and chopping profiles have been predicted using a combination of finite element analysis and optical design codes.
