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 with its spherical working surface on the supporting shoulder of the cylindrical opening of an intermediate cylindrical part, placed on the supporting shoulder of the cylindrical opening of a main holder. The method includes measuring the beat of the centre of curvature of the first working surface relative to the axis of rotation; rotating the intermediate part of the holder to align the centre of curvature of the first working surface with the axis of rotation and fixing its position; tilting the lens to align the centre of curvature of the second working surface with the axis of rotation or placing the lens perpendicular to 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 with a supporting shoulder for mounting the lens is inserted. The internal cylindrical opening of the intermediate cylindrical part is offset relative to its external cylinder, and the internal cylindrical opening of the main holder has the same offset relative to the reference axis of the main holder.

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