Details

Calcium Fluoride (CaF2) Plano Convex (PCX) Cylinder Lenses focus incident light onto a line with a positive focal length. They consist of a plane and a convex cylinder and are commonly used to focus parallel or divergent light beams onto a line or change the aspect ratio of an image.
Calcium fluoride material has a wide transmission spectrum range (180nm-8.0 μ m). It has the characteristics of high damage threshold, low fluorescence, high uniformity, etc. Its physical properties are relatively soft, and the surface is easy to scratch. It is often used for laser collimation and is also commonly used as a substrate for various optical components. In order to reduce spherical aberration, when converging the collimated beam into a line, the collimated light should be incident from the curved surface of the lens, while when aligning the linear light source, the linear light source should be incident on the plane of the lens.
The calcium fluoride flat convex cylindrical lens of Guangtan Intelligent has lenses of various sizes and focal lengths, providing coated and uncoated products. The broadband anti reflection film provided can be used in the IR1 (infrared 3-5 μ m) band. Guangtan Intelligent can also customize lenses of other specifications according to your actual application needs.
