Product Description

Product Description: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), has the characteristics of high damage threshold, low fluorescence, high uniformity, etc., soft physical properties, easy to scratch the surface, often used in laser Collimation, used as a substrate for a variety of optical components. A biconvex lens will focus light into a point with a positive focal length, consisting 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 larger the conjugation ratio, the larger the generated aberration.
