Product Description
Bi-concave lenses can diverge a collimated beam from a virtual focus and are commonly used in a Galilean-type beam expanders. Bi-Concave lenses have a negative focal length and are always used to diverge a collimatedor converging beam. Boxin provide plano-concave lenses of many materials, such as N-BK7, UV fused silica, SF,CaF2, MgF2, ZnSe, ZnS, and so on.
