ALIGNMENT DEVICE Russian patent published in 2006 - IPC G02B7/18 

FIELD: the invention refers to the field of precise instrument manufacturing and may be used for alignment of optical elements in devices with changing parameters of environment and working under vibration and percussive influences.

SUBSTANCE: the alignment device has a body, an optical element with slants, adjusting screws and elastic elements installed opposite to adjusting screws and interacting with slants on the optical element. At that each elastic element is fulfilled in the shape of a screw made hollow with inner opening which longitudinal axle coincides with the longitudinal axle of the screw, between the screw and the optical element there is an intermediate washer of conical form , the conical surface of which is mated with reciprocal slant of the optical element and in the bow part of the screw there are slits fulfilled transparent and communicable with the inner opening of the screw. At that the slits are fulfilled cruciform and transversal with each other and with the longitudinal axle of the screw.

EFFECT: increases accuracy, decreases receptivity to exterior influences and dimensions.
