Abstract
An apparatus is disclosed for aligning optical beams from a source to a destination. The apparatus comprises a first pair of cylindrical lenses comprised of a first cylindrical lens and a second cylindrical lens. The first and second cylindrical lenses are adapted to slide up and down or back and forth along first and second line segments. The first and second line segments can be parallel to each other. A second pair of cylindrical lenses is disclosed comprised of a third cylindrical lens and a fourth cylindrical lens. The third and fourth cylindrical lens are adapted to slide up and down or back and forth along a third and fourth line segments. The first, second, third, and fourth line segments can be parallel to each other. The first, second, third, and fourth cylindrical lenses can adapted to slide between an optical source and an optical destination. The first and second cylindrical lenses, and the third and fourth lenses respectively can be closely adjacent one another. The cylindrical lenses can be constructed in various manners including cutting out portions of original cylinders and providing index of refraction material variations. A first mirror and/or a second mirror can also be provided to provide a multiple pass through embodiment.
