YuTai Optics Double-Concave Lens
Yutai Optics
A double-concave lens is compose of two concave surface, has a negative focal length and are best used to diverge a converging beam. Similar to a plano-concave lens, a bi-concave lens can diverge a collimated beam to a virtual focus like a beam expander.
