Paper Abstract

Optical angle gauge is one of the measuring instruments standardized by the National Metrological System of Chian for verification of plane angle. In this paper a new method for verifying the optical angle gauge is described and a related photoelectric goniometer developed by ourself is introduced. As a datum instrument for measuring deviation angle of optical wedge, its maximum error is less than 0.1 inch. In addition, some examples of its application for calibrating indication error of various angle measuring devices are presented, and its distinctive advantages, especially in calibrating 2D autocollimators, are demonstrated.
