Abstract
Abstract A laser beam pointing aid for field testing of breadboard laser systems andtilizing a hollow housing with apertures at each end and with crosshairs at one end of the housing and a telescope adjustably mounted to the hollow housing and being positionable relative to an output beam from a laser system to allow one to utilize the last mirror of the laser system and the laser beam pointing aid to accurately point the laser beam to a target.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
116 words
A device for pointing a laser beam to a remote target comprising an elongated housing having an adjustable iris as an input aperture at one end and an output aperture at an opposite end, a center line axis through said housing and said input and output apertures, an unobstructed path through said housing along said center line axis of said housing for passing a laser beam therethrough, a telescope, means mounting said telescope relative to said housing, a center line axis through said telescope, and said means mounting said telescope being such to allow one to boresight said telescope and align the center line axis of the telescope with the center line axis of said housing.
Claim 2
Independent Claim
116 words
A device for pointing a laser beam to a remote target comprising an elongated housing having an adjustable iris as an input aperture at one end and an output aperture at an opposite end, a center line axis through said housing and said input and output apertures, an unobstructed path through said housing along said center line axis of said housing for passing a laser beam therethrough, a telescope, means mounting said telescope relative to said housing, a center line axis through said telescope, and said means mounting said telescope being such to allow one to boresight said telescope and align the center line axis of the telescope with the center line axis of said housing.
Claim 3
Dependent Claim
40 words
A device as set forth in claim 1, wherein said output aperture has mounting brackets therearound for allowing a ring with crosshairs thereon to be accurately positioned relative to said output aperture for aiding in boresighting the center line axis.
Claim 4
Dependent Claim
47 words
A device as set forth in claim 1, wherein said device is mounted beside a universally mounted mirror that is designed to be adjusted in three dimensions and reflect an output laser beam through said input and output apertures along said center line axis of said housing.
