Rod and cone lenses

Rod lenses are a variant of cylindrical lenses used to focus incident light into a line. The outside faces of the lens are typically ground & outside diameter polished. These lenses are often used for generating line images from circular laser beams.

Cone lenses are rod lenses with a conical point, and are used by shining incident light along the long axis of the lens to create a circular illumination pattern. The diameter of these lenses are often ground to reduce stray light.

Knight optical offer custom rod and cone lenses in a range of sizes and materials to suit our customer’s applications.
Custom lenses may be AR coated for improved transmission.
