Patent ID: 8066389

Claim:
A beam alignment chamber extending in a length direction comprising: a base having a front edge and two side edges; first and second side walls connected to the base, and extending along the length of the beam alignment chamber; a front wall located at the front edge of the base having an output opening; a plurality of light sources disposed to direct light beams through the first or second side walls, each light beam being uncorrected for divergence with respect to at least one axis; a plurality of reflectors mounted on the base, each having independent yaw and pitch adjustments, each paired with at least one corresponding light source, the base-mounted reflectors being disposed to direct the light beams from the corresponding light sources along the length of the beam alignment chamber through the output opening forming an aligned array of parallel light beams, the optical distance between each light source and the output opening being substantially equal for each of the light beams; and one or more optical elements positioned in the optical path of the aligned array of light beams disposed to correct the beam divergence with respect to at least one axis.
