Abstract

The Space Based Visible sensor is a high straylight rejection telescope whose performance is driven by the low scattering surfaces of its primary and secondary mirrors. The scattering performance of these mirrors is a function of the level of particulate contamination inside the telescope housing during ground processing, launch, and flight. This report describes a test program undertaken at Lincoln Laboratory to minimize the creation and spread of metallic particulates generated from the fasteners used in telescope packaging. Issues such as fastener material, insert material, lubrication, locking methodology, and insert type are described.
