UV Fused Silica Bi-Concave Spherical LensesThorlabs' UV-fused silica Bi-Concave lenses are popular for many applications. They are available uncoated or with a UV AR coating. Bi-Concave lenses have a negative focal length and are best used to diverge a converging beam. Bi-concave lens can diverge a collimated beam to a virtual focus and are commonly used in Galilean-type beam expanders.
