OPTICAL-MECHANICAL SYSTEM Russian patent published in 2016 - IPC G02B26/08 H01S3/225 

FIELD: optics.

SUBSTANCE: optical-mechanical system comprises flat reflecting mirror installed with possibility of changing its position under action of movement mechanism so that one stable position provides passage of light beam from the radiation source to the output window, and in the other position this beam is deviated towards the trap. Movement mechanism comprises electromagnet with moving armature, which is connected by rod with flat reflecting mirror and provides its movement from position when the light beam is directed into trap to position when the light beam is directed to output window. Movement mechanism also includes return spring, which serves to return the flat reflecting mirror from the position when the light beam is directed to output window to position when the light beam is directed into trap. In the passage route of light beam from flat reflecting mirror to the trap there is additional re-reflecting spherical mirror.

EFFECT: technical result consists in increasing reliability and increasing service life.
