djtraximus has added a video to the pool:
A green 1000mw laser is placed about 20m away from a purpose built laser bounce mirror. The beam is targeted at the mirror which reflects the beam. Beam reflection direction can be controlled by adjustable handles and small thumb screws on the mirrors for precise alignment. This was an experiment to set up the laser beam targeting. Some mirrors are diffreaction gratings which can disperse the reflected beam into hundreds of beams. That is what I thought I orderd but not to be. These are very high grade mirrors used.
