The typical application of plano convex cylindrical lenses is to shape deformed light beams using a pair of cylindrical lenses. A pair of plano convex cylindrical lenses can be used for collimating and circularizing the output of laser diodes. Another possible application is to use a single cylindrical lens to focus the diverging beam onto the detector array.
In order to minimize spherical aberration, when converging a collimated beam into a line, the collimated light should be incident from the curved surface of the lens, while when using a collimated light source, the line light source should be incident on the plane of the lens.
