An optical element support is described which is 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.
