Double-Convex (DCX) Lenses, D=25.40mm, F=25.40mm, Uncoated CaF2 Single Crystal, United Optical Technology Co., Ltd (CAT#: STEM-OP-0775-YJL)

Double-Convex (DCX) Lenses, D=25.40mm, F=25.40mm, Uncoated CaF2 Single Crystal, model 110139, is manufactured by United Optical Technology Co., Ltd.
Calcium Fluoride (CaF2) Double Convex Lenses are biconvex lenses based on calcium fluoride.
Calcium fluoride material has a wide transmission spectrum range (180nm-8.0μm), high damage threshold, low fluorescence, high uniformity and other characteristics. The physical properties are soft and the surface is easy to scratch. It is often used in the collimation of lasers and is used as the base of a variety of optical components.

A lenticular lens focuses light into a point with a positive focal length and consists of two convex surfaces of equal radius. Commonly used in imaging relay systems and object imaging at limited conjugate distances. The characteristic is that the greater the conjugation ratio, the greater the aberration produced.
