Cone lens


He Rui optics cone lens, also known as a conical lens or a gradient index lens, is a type of lens that has a curved surface with a profile that resembles a cone. This lens can focus or diverge light depending on its shape and the material it is made from.

When specifying a cone lens, several parameters are important, including the cone angle, clear aperture (the size of the lens), focal length, material, and any coatings that may be required for specific applications.
