Abstract

Referring to Figure 1, disclosed is an apparatus 10 for coupling two laser light beams in order to create a dual light source for a raster scanning system. The apparatus 10 is capable of adjusting the distance between the two light beams to provide the required separation between the two light beams for any rater scanning system. This apparatus 10 utilizes two laser light sources 12 and 14, two collimating lenses 16 and 18 and an adjustable right angle mirror wedge 20. The two light sources 12 and 14 are placed across from each other. The light beams 22 and 24 from the two laser light sources 12 and 14 are directed onto the mirror wedge 20 with an angle of incidence of 45 degrees. The collimating lens 16 is located in the path of the light beam 22 from the laser source 12 to the mirror wedge 20 and the collimating lens 18 is located in the path of the light beam 24 from the laser source 14 to the mirror wedge 20. The mirror wedge receives the laser light beams 22 and 24 from both collimating lenses 16 and 18 respectively and reflects both light beams in a direction that is perpendicular to the original direction. Therefore, the reflected light beams 26 are parallel to each other.
