An optical assembly is provided for use with a laser alignment system that has a laser emitter and at least one photosensitive target. The optical assembly includes first and second 90° pentaprisms disposed for receiving an input beam produced by the laser emitter. The first and second 90° pentaprisms are oriented to produce first and second reflected beams that are parallel to one another. The optical assembly further includes first and second beam diverters disposed and oriented to receive the reflected beams from the first and second 90° pentaprisms and to produce first and second output beams that are mutually perpendicular. The first and second 90° pentaprisms may be see-through pentaprisms to produce a third output beam that is colinear with the input beam and perpendicular to the first and second output beams.
An optical assembly, comprising:
A laser alignment apparatus, comprising:
A laser alignment system, comprising:
The laser alignment system of clam 13, wherein the first and second beam diverters comprise 45° pentaprisms, diffracting prisms, mirrors or lenses.
