Description
General Introduction: Raytek biconvex lens consists of an incident plane and a shooting plane, and its characteristic is that the focal length of the middle part of the lens plane is long, and the focal length of the ends of each lens plane is short. Dual convex lenses are mainly used for converging light from point sources or transferring images to other optical systems.
