Plano concave cylindrical lenses are similar to plano-concave spherical lenses, but plano concave cylindrical lenses only work on one axis. These cylindrical lenses are used for applications that require shaping of point light sources in one dimension. A typical application is to use a single cylindrical lens to convert a collimated laser beam into a line beam.
A pair of cylindrical lenses can be used to reshape the image. In order to minimize spherical aberration, when the beam is divergent, the light should be removed from the lens. Surface incidence. Plano-concave cylindrical lenses can provide uniaxial negative imaging for deformed beam expansion and a wide range of applications.
