Abstract

A right-angle prism is quite foundational optical element. Its many transmission paths found within it have been utilized for corresponding particular uses. In this paper, so called new properties of the right-angle prism mean an additional transmission path newly found and temporarily named as ABCDEF light ray which exists in the prism. Demonstrating the new conditions and scopes of the new properties are addressed by use of graphic representation and mathematical expression. The new properties can initiate new applications. Three of them are listed in this paper: (1) for bidirectional `right-angle pentaprisms'; (2) for view-finder of autocollimators; (3) for explaining causes of spurious star-image.
