Plano-Convex (PCX) Cylinder Lenses, D=25.4*mm, F=200.00mm, Uncoated CaF2 Single Crystal, United Optical Technology Co., Ltd (CAT#: STEM-OP-2619-YJL)

Plano-Convex (PCX) Cylinder Lenses, D=25.4*mm, F=200.00mm, Uncoated CaF2 Single Crystal, model 158006, is manufactured by United Optical Technology Co., Ltd.
Calcium fluoride material has a wide transmission spectrum range (180nm-8.0μm). It has the characteristics of high damage threshold, low fluorescence, high uniformity, etc. It has soft physical properties and is easy to scratch on the surface. It is often used in the collimation of lasers and is often used as the substrate for various optical components. In order to reduce spherical aberration, when converging a collimated beam into a line, the collimated light should be incident from the curved surface of the lens, and when collimating a linear light source, the linear light source should be incident on the plane of the lens.

Calcium Fluoride (CaF2) Plano Convex (PCX) Cylinder Lenses focus the incident light onto the line and have a positive focal length. Composed of a flat surface and a convex cylinder, it is often used to focus parallel or divergent beams onto a line or to change the aspect ratio of an image.
It has the characteristics of high damage threshold, low fluorescence and high uniformity.
