ABSTRACT:
An optical collimating, laser ray target position indicating and laser ray absorbing device, mounted between a laser generating source and a laser ray guiding device. The device includes a reference light source for facilitating optical collimation of the laser system and for indicating the target position of the laser ray, a first movable reflecting mirror set 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 which may be moved into or away from an operating position where light, a third movable reflecting mirror set, which includes a fourth reflecting mirror and a fifth reflecting mirror and may be moved into or away from an operating position where the fourth reflecting mirror interrupts, by reflecting, light from the laser generating source and the fifth reflecting mirror reflects light coming from the reference light source and reflected by the first movable reflecting mirror set disposed at the second position thereof to the laser ray guiding device for indicating the target position of the laser ray, and an absorption device for absorbing the laser ray coming from the laser generating source and reflected by the fourth reflecting mirror of the third movable reflecting mirror set.
