Product Description

Product Description:Calcium Fluoride (CaF2) Double Concave (DCV) Lens is a kind of double concave lens based on calcium fluoride.

The calcium fluoride material has a wide transmission spectrum range (180nm-8.0 μ m). It has high damage threshold, low fluorescence, high uniformity and other characteristics. Its physical properties are soft, and its surface is easy to scratch. It is often used for laser collimation, and also used as the base of a variety of optical elements, such as lenses, window pieces, etc. The biconcave lens will radiate the light with a negative focus, which is composed of two concave surfaces with equal curvature. It is commonly used for beam expansion, projection and focal length expansion of the optical system of the lens.
