Fused Silica Double-Concave Lens

Product Overview
The Fused Silica Double-Concave Lens is an optical element made from high-purity fused silica. It features two concave surfaces with equal curvatures, designed to increase the divergence of a light beam. This lens is commonly used in optical systems to alter the focusing characteristics of light, particularly for applications such as expanding the focal length of optical systems, beam expansion, image reduction, and projection. Due to its negative focal length, the fused silica double-concave lens effectively diverges parallel incident light.
