An optical lens is an optical element made of transparent materials (such as optical glass, resin, etc.). The optical lens is a refracting lens. The refraction surface of the lens is a transparent body with two spherical surfaces (part of the spherical surface), or one spherical surface (part of the spherical surface) and one plane. The optical lens is the most basic optical element that composes the optical system, such as objective lens, eyepiece, condenser, etc. The components are composed of a single lens and multiple lenses.

   Cylindrical lens are designed for applications that require one-dimensional shaping of the light source. They have flat-concave and flat-convex structures, both of which are used to diverge or converge the beam. It is generally used to focus incident light on a line or to change the aspect ratio of the image. Cylindrical mirrors have a cylindrical surface that enables incident light to be focused in a certain dimension and stretch the image. The focal length of the cylindrical lens can be negative or positive, which is suitable for laser line generation or deformed beam shaping to circulate the laser output. A variety of cylindrical mirrors can be provided, including colorless optical glass, laser crystal, fused silica, anti-radiation glass, ultraviolet and infrared materials, metal materials, such as SiO2, CaF2, BaF2, ZnSe, ZnS, etc. All materials can be selected without coating or with antireflection coating. Cylindrical lenses, non-cylindrical lenses, and cylindrical achromatic cemented lenses are also available.
