LENS IN MOUNT Russian patent published in 1995 - IPC

FIELD: optoelectronics. SUBSTANCE: optical element 1 has a number of grooves which sides are parallel to its optical axis on its generating line. Keys 3 are entered into these grooves through holes in mount 2 for radial slipping and are made fast to cylindrical part of mount. Keys are manufactured from material which linear expansion factor is close to that of optical element. With change of temperature dimensions of mount and optical element vary differently. In this case key 3 slips in grooves of optical element in radial direction maintaining centering of optical element. EFFECT: expanded application field. 2 dwg
