Cylindrical lenses are either Plano-convex or Plano-concave in form and rectangular in shape. These lenses are used in applications requiring magnification only, such as in transforming a point image into a line image or changing the height of an image without changing its width or vice versa. Therefore serves a variety application, such as slit line detector array illumination, bar code scanning, holography, optical information processing and computer, laser projection.
