Abstract

The Instituto de Astrofisica de Canarias infrared camera is intended as a common user instrument for the Cassegrain focus of the Carlos Sanchez Telescope at the Observatorio del Teide. The camera will be equipped with a 256 X 256 InSb array, two filter wheels and a centered diamond turned aluminum optical system working at liquid nitrogen (LN2) temperature. This paper presents the mechanical design, tolerancing and development of the mirrors system, as well as the fabrication and testing of the optical elements.
