Details

The K9 plano convex cylindrical lens focuses the incident light onto a line with a positive focal length, consisting of a plane and a convex cylindrical surface.
Flat convex cylindrical lenses are the preferred choice for one-dimensional magnification applications. A typical application is to shape deformed light beams using a pair of cylindrical lenses. 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. K9 optical glass is a type of optical material with excellent broad-spectrum transmission. It has high transmittance from 350nm to 2000nm, high hardness, and can withstand various physical and chemical stimuli. It has low content of bubbles and impurities and is often used as a substrate for various optical components.
The K9 plano convex cylindrical lens of Guangtan Intelligent offers a variety of lens sizes and focal lengths, with coated and uncoated products to choose from. It also has a broadband anti reflective film that can be used in the VIS (visible light) band, NIR (near-infrared) band, and SWIR (short wave near-infrared) band to meet your applications in different scenarios and bands. Guangtan Intelligent can also customize lenses of other specifications according to your actual needs.
