LENS IN MOUNT Russian patent published in 1995 - IPC

FIELD: optoelectronics. SUBSTANCE: lens in mount has optical elements 1-3, mounts 4 and 5 locking rings 6 and 7. Butts of mounts 4 and 5 and locking rings 6 and 7 stand duty as limiters of displacement of optical elements 1-3 along axis. Thermal compensators 8 prevent displacement of optical elements sidewise to axis. Local recessions which flat butt surfaces contact perpendicular axes with planes of protrusions on mount 4 and rings 6 and 7 are made over periphery of bulging surfaces of optical elements 1 and 3. Recessions in second surface of element 1 are displaced relative to recessions on its first surface through half of angle between them. EFFECT: improved functional capabilities. 2 cl, 3 dwg
