Cylinderical lenses are mainly used for design requirements that change the size of the imaging dimension. For example to convert a spot into a line spot or to change the height of an image without changing the width of the image

A cylindrical lens in appearance like PCX lens, but a cylindrical lens concentrates light in only one direction and is partially cylindrical (as opposed to spherical). They are useful for making laser light generators, extending images, concentrating into narrow or converging rays, barcode scanning, laser projection, vision inspection, etc.
