Plano-convex cylindrical lenses focus incident light onto a line with a positive focal length, consisting of a flat surface and a convex cylindrical surface, and are often used to focus parallel or diverging beams onto a line or to change the aspect ratio of an image. Plano-concave cylindrical lenses consist of a plane and a concave cylinder with a negative focal length and are often used to focus parallel or diverging beams onto a line or to change the aspect ratio of an image.
Jingsheng Optoelectronics Technology offers uncoated and AR-coated cylindrical lenses. AR coating options include UV, VIS, NIR, and SWIR. Germanium silicon, or zinc selenide substrates are suitable for infrared applications, and fused silica is suitable for ultraviolet applications.
