Abstract

A mechanical design has been developed for the Telescope Optical Assembly (TOA) of the Optical Communications Demonstrator (OCD). The TOA is the portion of the OCD instrument that integrates all the optical elements of the system with the exception of the Laser Transmitter Assembly (LXA) which is fiber coupled to the TOA. The TOA structure is composed primarily of aluminum components with some use of steel and invar. The assembly is contained within a 16 cm MUL 20 cm X 33 cm envelope and has an estimated mass of 5.5 kg. The mechanical design was developed using Computervision's CADDS 5 computer aided design software. Code V optical design data was used as a primary input and was efficiently and accurately transferred form the optical designer to the mechanical designer through the use of IGES files. In addition to enabling rapid transfer of the initial optical design as well as subsequent optical design refinements, the IGES transfer process was also used to expedite preliminary thermal and dynamic analyses.
