SYSTEM FOR CONVERTING LASER RADIATION OF GUIDING MECHANISMS Russian patent published in 2009 - IPC F41G7/26 

FIELD: physics.

SUBSTANCE: system can be used in mechanisms for guiding guided missiles to a target using a laser beam. The system includes an input window of the laser modulation device, first pancratic system and first objective lens placed lying on the first axis, second pancratic system, second objective lens and optical compensator lying on the second axis, parallel the first axis. The first reflector is placed at an angle to the first axis in front of the first pancratic system with possibility of coming out of the beam path. The second reflector is placed in front of the second pancratic system parallel the first reflector. In the initial position of the first reflector on the axis of the first pancratic system, mobile components of the second pancratic system move, thereby reducing angle of divergence α of the laser radiation in the near control area to a value α_d. When the first reflector moves out of the beam path, mobile components of the first pancratic system move, thereby reducing angle of divergence of laser radiation in the far control area from value α_d to a minimal value. Each pancratic system includes at least two mobile components.

EFFECT: reduced length of the pancratic system, prevention of defocusing of the system in the entire movement range of lenses of the pancratic system.
