A method and apparatus for generating small angles for calibrating autocollimators or the like is described. It includes a small angle wedge which is rigidly attached to a mechanical beam which is rotatable about a pivot point. The rotation of wedge causes a very small deviation in the line of sight of an autocollimator under test after passing through the wedge and thus gives a large optical advantage.
