Abstract

Especially for space applications, the problems of seeing are being superceded by the problems of dimensional changes in remotely located optical systems. Conditions of operation, in addition to launch considerations of acceleration and weight, often include . vacuum environment . thermal cycling over wide temperature ranges . irradiation . passage of considerable time without replacement . fixed focus. In choosing materials, the usual figures of merit, shown in Table I, are a good starting point, but ignoring other considerations can lead to disaster. We discuss below a number of these considerations.
