THE LARGE APERTURE MIRROR SYSTEM HAVING THE AUTOMATIC ALIGNMENT MECHANISM THAT IS LESS SENSITIVE TO THE TEMPERATURE CHANGE USING LASER COLLIMATOR

摘要

The large-diameter reflective optical apparatus of the present invention has a barrel formed with an inlet and an outlet through which light is introduced, and is installed inside the barrel to collect light flowing through the inlet, and includes a main reflector having a through part through which light is emitted. It is provided in front of the reflector to reflect the light collected by the main reflector to pass through the through and the outlet, the output unit for receiving the light reflected from the sub-reflector and outputs the image, the laser to the main reflector The laser collimator to be irradiated, rotatably provided on the side of the path of the light flowing into the output unit, and includes a shutter mirror having a reflection mirror for selectively reflecting the laser irradiated from the laser collimator to the laser collimator according to the rotation do.
