Abstract
Abstract A simply structured apparatus for mounting two lasers to produce controlled mutual parallelism or colinearity of the beams by simple operations comprises a frame with mutually perpendicular walls to which two laser-amounting plates are individually affixed. Two adjusting screws are provided for controllably aiming lasers individually by causing their supporting plates to flex in mutually perpendicular directions.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
158 words
An apparatus for mounting two lasers to produce controlled parallelism of the beams therefrom comprising a frame having a first wall surface and a second wall surface which are perpendicular to each other, a first plate for affixing a first laser thereon, said first plate being flexibly affixed to said first wall surface along an edge which is normal to said second wall surface, a second plate for affixing a second laser thereon, said second plate being flexibly affixed to said second wall surface along an edge which is normal to said first wall surface, a first adjusting screw adapted to move in the direction normal to said first wall surface and to thereby cause said first laser to move parallel to said second wall surface, and a second adjusting screw adapted to move in the direction normal to said second wall surface and to thereby cause said second laser to move parallel to said first wall surface.
Claim 2
Independent Claim
158 words
An apparatus for mounting two lasers to produce controlled parallelism of the beams therefrom comprising a frame having a first wall surface and a second wall surface which are perpendicular to each other, a first plate for affixing a first laser thereon, said first plate being flexibly affixed to said first wall surface along an edge which is normal to said second wall surface, a second plate for affixing a second laser thereon, said second plate being flexibly affixed to said second wall surface along an edge which is normal to said first wall surface, a first adjusting screw adapted to move in the direction normal to said first wall surface and to thereby cause said first laser to move parallel to said second wall surface, and a second adjusting screw adapted to move in the direction normal to said second wall surface and to thereby cause said second laser to move parallel to said first wall surface.
Claim 3
Dependent Claim
49 words
The apparatus of claim 1 further comprising a means to reflect a light beam and a beam combining means for combining two beams of light, said reflecting means and said beam combining means being disposed so as to receive beams from said lasers and to produce mutually colinear beams.
Claim 4
Dependent Claim
17 words
The apparatus of claim 1 wherein said frame includes three-point mounting means for adjustably orienting said apparatus.
