Paper Abstract

This paper presents the design, fabrication and metrology results and the assembly and verification process of the LSST camera ceramic optical bench structure utilizing the unique manufacturing features of HB-Cesic technology. The optical bench assembly consists of a rigid “Grid” that supports individual raft plates, upon which the CCD sensor assemblies are mounted by way of a rigid kinematic support system. This structure allows it to meet stringent requirements for the focal plane planarity and thermal and mechanical stability.
