Plano Concave Cylindrical Lens

Cylindrical lenses are generally used to focus incoming light onto a line or to change the aspect ratio of an image.They are usually linear and control the direction of the light beam.A cylindrical lens has a cylindrical surface that enables incident light to focus on a dimension and stretch the image. The focal length of the cylindrical mirror can be negative or positive and is suitable for laser line generation or deformation beam shaping to cyclize the laser output.Cylindrical lens compared with general spherical lens, cylindrical lens production will be difficult, to reasonable selection of materials, pay attention to the texture of the material, bubbles, impurities, uniformity and other characteristics, pay attention to the product specifications and quality control, such as scratches, dents, luster, high quality grinding technology.

Combined with a plano convex cylindrical,Plano Concave lens can be used to shape the elliptical beam of a semiconductor laser into a circular beam, Plano concave cylindrical can be used in projection system, imaging system, optical instrument, laser measurement system. Processing materials can be optical glass, laser crystal, fused quartz, ULTRAVIOLET and infrared materials, metal materials.
