Plano-Concave Cylindrical Lens
 
Cylindrical lens is used to provide focusing power in one section only. For illumination or detection of light from line sources. Also used to anamorphic compression of beams and images. Especially widely used to anamorphic compression of LD (laser diode) output beam.
