Abstract
The primary pointing and tracking telescope on the HABE optical payload is a 60 cm, clear-aperture, Cassegrain telescope. This paper presents the requirements for the telescope, a description of the optical, structural, and thermal design, the manufacturing process, and the performance test results. The telescope is required to have very high optical quality, a cryogenic system for actively cooling the primary mirror, a remote-controlled mechanism to refocus the secondary mirror, a baffle system to effectively reject off-axis radiation, and a wide-band optical coating. In addition, the telescope needs to be lightweight and stable over a wide temperature range during operation. The telescope has been successfully designed, fabricated, and delivered.
