REGULATED OPTICAL MODULE Russian patent published in 2009 - IPC G02B7/00 

FIELD: physics; optics.

SUBSTANCE: proposed invention relates to optical instrument making and can be used in optical systems with high requirements for their regulation. The regulated optical module consists of an outer casing and optical element, fitted along an optical axis and joined to each other through a displacement mechanism. The optical element is fitted with possibility of moving along the optical axis. The displacement mechanism is a micro-adjustable jack and consists of a monolithic case and a differential. There are spring elements on the side walls of the case. The bottom part of the case is rigidly fixed on the outer casing. The inner casing of the optical element is fixed on the upper part of the casing. The differential consists of a bolt and two nuts, with different pitch of thread P. One of the nuts is rigidly fixed on opposite inner walls of the case of the micro-adjustable jack. The other nut can be moved on the threads of the bolt. The actuator of the regulated optical module consists of a manipulator and an electric motor. Also the optical element can be made either in form of a lens or mirror or prism.

EFFECT: increased accuracy and reliability of operation of the regulated optical module for moving an optical element with subsequent locking in a given position with considerable simplification of the design.
