PROCEDURE ESTABLISHING ANGLE OF GLASS WEDGE Russian patent published in 2003 - IPC

FIELD: optics. SUBSTANCE: procedure establishing angle of glass wedge includes direction of parallel bundle of rays on to wedge, multiple passage of bundle of rays through wedge, recording of direction of bundle of rays going out of wedge and establishment of angle of wedge. Coincidence of incident and outgoing bundles is ensured by variation of angle of incidence of bundle of rays on to front face of wedge. Total number N of reflections of bundle of rays from faces of wedge is counted, angle l_i of incidence of bundle of rays is measured and angle θ of wedge is established. EFFECT: increased precision of establishment of angle of optical wedges with help of typical measurement aids and fixtures with use of simple technological operations. 1 dwg
