G-Lens
The G lens (G-lens), also known as a self-focusing lens or a gradient index lens, has focusing and imaging functions. Self-focusing lens is an essential basic component in optical communication passive devices, which is used in optical couplers, collimators, optical isolators, optical switches, lasers and so on.
