Lithium Fluoride Double-Concave Lens

Product Overview
The Lithium Fluoride (LiF) double-concave lens is an optical element with two inward-curved surfaces designed to effectively alter the direction of parallel incident light, enabling beam divergence or convergence. This lens is commonly used in infrared and ultraviolet optical systems for functions such as beam separation, focusing, and imaging. Its unique shape makes it an essential component in a variety of optical devices, particularly in instruments such as telescopes, microscopes, and spectrometers.
