Abstract

This paper describes the in-process testing of optical components machined on a Pneumo Precision MSG-325 diamond turning lathe. An unequal path Twyman-Green interferometer mounted on the X slide of the lathe provides the means to test aspheric profiles and complex conic shapes and locate conjugates. The use of this interferometer, together with other mechanical methods, enables tooling to be set and centred to the required level of accuracy.
