Bi-concave spherical lenses «In Stock»

Bi-concave spherical lenses feature two spherical concave surfaces with the same radius of curvature, while their focal length is negative. The performance of these lenses is best when used for finite conjugate (0,2X - 5X ratio) applications, most often to diverge converging light.
