Axicon Lens

Axicon focus lenses have one conical surface, and are used to produce a ring focus. Typically, axicon focus lenses have a second flat surface and are used in combination with a focusing lens.

Our high grade ZnSe Axicon lenses are made from a manufacturing process suited to the axicon angle and the accuracy required. For small angle, high accuracy lenses, the manufacturing process involves diamond-machining.
