Pivotal Support with Independent Adjusting Elements and Locking Means

摘要

This document discloses an optical element support capable of pivoting an optical element on its horizontal and vertical axes. The pivoting adjustments are facilitated by spaced threaded rods screwed into a support element and abutting a surface element extending from a receptacle containing the optical element. The surface element is capable of flexure without causing distortion of the receptacle. The optical element support has a locking element which prevents pivoting in the locking mode. (Author)
