Multiple laser beam generation |
摘要 |
A system which is preferably employed in a laser alignment instrument produces up to five orthogonal beams from a single laser diode beam. In one embodiment the optics take advantage of the elliptical shape of the beam from a laser diode which when collimated produces a plurality of orthogonal beams by reflection off a plurality of 45°-angled reflective surfaces intercepting outer portions of the beam. In one preferred embodiment a solid reflective element was four 45°-angled facets to produce four beams from outer portions of a preferably non-elliptical beam, and a fifth orthogonal beam is produced by transmission of a central portion of the beam through the element. The element can be solid glass, or it can be glass or other material with a central hole.
