An achromatic cylindrical lens can minimize chromatic aberration, so it can be used to focus a single direction of a multi-color light beam. Unlike a spherical lens that produces a point-focusing spot, an achromatic cylindrical lens can produce a linear focusing spot. Our cylindrical achromatic doublets are pre-installed in a Ø1" housing for ease of use. The housing is engraved with the part number, the range of the increased projection film, the focal length, the arrow indicating the direction the lens should face when the quasi-linear light source, and the infinity symbol indicating that the lens has an infinite conjugate ratio
