METHOD FOR CENTRING LENS IN HOLDER AND HOLDER THEREFOR Russian patent published in 2015 - IPC G01B11/27 G01M11/02 G02B7/02 

FIELD: physics.

SUBSTANCE: method includes mounting a lens on the flat shoulder of the intermediate part of a holder, placed on the shoulder of the cylindrical opening of the main holder and capable of tilting. The method includes rotating the main holder about its reference axis, measuring the beat of the centre of curvature of the first working surface of the lens relative to the axis of rotation thereof, tilting the intermediate part to align the centre of curvature of the first working surface of the lens with the axis of rotation and fixing the position of the intermediate part; measuring the beat of the beat of the centre of curvature of the second working surface of the lens relative to the axis of rotation; shifting the lens on the flat surface of the supporting shoulder to align the centre of curvature of the second working surface of the lens with the axis of rotation and fixing the position of the lens in the intermediate part of the holder. The holder has an external cylindrical base surface and a flat external base flange which form the reference axis of the holder, an internal cylindrical opening with a supporting shoulder in which the intermediate cylindrical part is inserted with an increased seating clearance, said intermediate cylindrical part having a flat supporting shoulder for mounting the lens. The intermediate cylindrical part is mated with the supporting shoulder of the internal cylindrical opening on a spherical surface.

EFFECT: high centring accuracy owing to centring on both surfaces of the lens.
