A plano-concave cylindrical lens is used to expand light in on axis. A negative cylindrical lens is able to diverge collimated input light away from a line. Plano-concave cylindrical lenses are used for one-dimensional compression of images, anamorphic beam shaping, and laser line generation.
A negative cylindrical lens acts like a flat concave spherical lens, but the former works only on one axis. These cylindrical lenses are used in applications where the point source needs to be shaped in a one-dimensional direction. A typical application is to convert a collimated laser beam into a linear beam using a single cylindrical lens. A pair of cylindrical lenses can be used to shape the image. To minimize spherical aberration, the surface of the lens should be oriented toward the source when diverging the beam.
