Bi-concave lens element GCL-0104 series

BK7visible

Bi-concave lenses have a negative focal length and are best used to diverge a converging beam. Bi-concave lenses can diverge a collimated beam to a virtual focus and are typically suitable for applications where the absolute conjugate ratio is close to 1:1.
