Abstract
A laser scanner which includes a light source which emits a light beam and a scanning mirror rotatable about an axis which reflects the light beam through a tilted protective window toward a scanning area and which directs return light from objects toward receiving optics. The laser scanner may include a collecting mirror which receives the return light, and an interference filter disposed between the collecting mirror and the scanning mirror. The window may include an anti-reflective coating which reduces reflection of internally scattered light. The tilted window may direct the reflective component of internally scattered light into a zone where an energy light absorber is present. A bulkhead system which may include a separation baffle may be provided to prevent light incident on the interference filter at an angle which is below an acceptance angle of the interference filter.
