Optical collimating, laser ray target position indicating and laser ray absorbing device of a laser system

摘要

The invention relates to an optical collimating, laser ray target position indicating and laser ray absorbing device, mounted between a laser generating source 10 and a laser ray guiding device 70, comprising a reference light source 20, generating a reference light for facilitating the optical collimation of the laser system and for indicating the target position of the laser ray; a first movable reflecting mirror set 30, reflecting light from the reference light source 20, which may be optionally disposed at a first position for performing optical collimation or at a second position for performing laser ray target position indication; a second movable reflecting mirror set 40 which may be moved into or away from an operating position where light, coming from the reference light source 20 and reflected by the first movable reflecting mirror set 30 disposed at the first position thereof, may be reflected to the laser generating source 10 for optical collimation purpose; a third movable reflecting mirror set 50, which includes a fourth reflecting mirror 55 and a fifth reflecting mirror 56 and may be moved into or away from an operating position where the fourth reflecting mirror 55 interrupts, by reflecting, light from the laser generating source 10 and the fifth reflecting mirror 56 reflects light coming from the reference light source 20 and reflected by the first movable reflecting mirror set 30 disposed at the second position thereof to the laser ray; and an absorption device 60 for absorbing the laser ray coming from the laser generating source 10 and reflected by the fourth reflecting mirror 55 of the third movable reflecting mirror set 50.
