Cylindrical Fresnel Lenses
A cylindrical Fresnel lens is a collapsed version of a conventional cylindrical lens. These lenses can be used in any application that requires focusing in only one dimension of the focal plane. In some cases, two separate cylindrical lenses may be combined to obtain different focal properties in the x and y dimensions of the focal plane; these configurations are representative of one type of anamorphic optic. A variety of cylindrical Fresnel lenses are available, with typical f-numbers between f/1 and f/2. Both positive and negative focal lengths are available as standard parts:
