FIELD: optoelectronics. SUBSTANCE: device includes case 1, mount 2 with optical element 3, centering rollers 4 placed in grooves of supporting case parallel to axis of device and put on axles 6 rigidly coupled to mount 2. Mechanism used to move mount 2 is composed of screw 7 which two threaded sections are fitted with nuts 8 and 9, pins contacting mount 2 and anchored on lever and pin made fast to mount and entering groove of nut 8. In static position rollers 4 do not allow optical element to change its position and specified pins prevent tilting of mount. In dynamics design provides for translational motion of optical element without tilting. EFFECT: improved reliability of focusing. 2 dwg
