Difficulties in prism processing technology

Abstract

The prism is one of the most important optical components in optical system, this paper analyzes the difficulties in processing technology. The angle accuracy of prisms can be improved by using slotted flat die, metal optic tooling, glass optic tooling and optic bonding tools. In this paper, the method of obtaining angle precision of prism with different batch and different precision grade is given, it has certain guiding significance for prism machining.
