Paper Abstract

A review of engineering philosophies used for the design of optical systems launched into space and operating a vacuum or cryovacuum environment is presented herein. Sources of energy dissipation which are usually lumped under a single modal parameter denoted as the equivalent viscous damping coefficient are reviewed. Optical systems operating in a cryovacuum environment are especially difficult to design for the launch inertia and acoustic loadings unless the components of the system are either caged or clamped since general viscoelastic effects, interface and/or joint relative motion are designed to be minimal. Moreover, stress levels and stress gradients are also designed to be low in precision instruments.
