Focuses light in only one dimension. Similar to a PCX lens in profile, but is a portion of a cylinder instead of a sphere. Cylinder lenses can transform a point of light into a line image. This is useful for making laser line generators. The lense magnifies in one dimension so it can be used for stretching images. Can be used for focusing light into a slit or converging light for a line scan detector.

Cylindrical lens can be used together with PCX oblong cylinder lenses for beam expander applications.

The thin lens approximation for the length of a line generated by a negative cylinder lens is:L = 2 * (r0/f) * (z + f)where L is the line length, r0 is half the beam diameter, z is the projection distance, and f is the focal length of the lens.
