A cylindrical lens is a lens which focuses light into a line instead of a point, as a spherical lens would. Plano-concave cylindrical lenses are designed to expand the light, it can be supplied in either diameter or rectangular shape for ease of mounting. Plano-cave cylindrical lenses are useful for laser line generation, anamorphic beam shaping and one-dimensional compression of images.
