METHOD OF ADJUSTING MICROSCOPE LENS AND MICROSCOPE LENS Russian patent published in 2013 - IPC G02B21/02 G02B7/02 

FIELD: physics.

SUBSTANCE: method involves preliminary measurement of instrument errors of lens units and calculating therefrom variation value of one of the air spaces and turning angles of each of lens unit about the axis of the external cylinder of the lens unit. Axial shift and turning of all lens units is carried out. The optical and mechanical axes of the lens are superposed via radial shifting of all lens units. The lens has, inside the cylindrical opening of the housing with a supporting end plane and an outer threaded base cylinder, lens units in a common cylindrical holder capable of axial displacement relative the supporting end plane, and a spacer adjustment ring and a spring for elastic axial closing of the common cylindrical holder. The lens is provided with a cylinder bushing with a recess directed along the axis of the cylindrical opening of the housing; the bushing is rigidly connected to the common cylindrical holder of the lens units in a radial direction and elastic closing in the axial direction by a spring. The bushing can move along the axis of the cylindrical opening of the housing and turn about that axis. The cylindrical opening of the housing has an eccentricity Δ_k relative the outer threaded base cylinder of the lens, and the inner opening of the common cylindrical holder of the lens units has an eccentricity Δo relative the outer cylinder of the common cylindrical holder.

EFFECT: high quality of adjustment while enabling automation thereof.
