Abstract

The Large Synoptic Survey Telescope (LSST) camera will be the largest camera ever constructed for astronomy. When light enters the camera it will first pass through the two large lenses of the L1-L2 Lens Assembly. This assembly consists of a 1.6 m spherical lens and a 1.2 m aspheric lens held in critical alignment by a carbon fiber composite structure. The structure is mounted to the camera structure by six adjustable struts, which provide the mechanism to align the L1-L2 Assembly to the rest of the camera optical system. Final optical performance of this assembly is based upon lens figure, lens alignment, and alignment stability. With manufacture of the individual components of the L1-L2 Lens assembly and testing of the integrated composite structure nearing completion, design, design drivers, and test results will be presented.
