Bi-concave spherical lenses «In Stock»

Bi-concave spherical lenses feature two spherical concave surfaces with 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 diverge converging light.
