Gradient Index Lens-Glens
Description
A cylindrical lens made by special technology, with the advantages of light weight, small size and easy installation. Its internal refractive index distribution decreases smoothly from the center to the edge. The unique flat end face and cylindrical structure make it easier to install and fix. It has the convergence, collimation and imaging functions that are difficult to achieve with conventional optical components.

Features
Its small diameter can miniaturize the structure of the optical system and make it easy to connect and assemble with other devices. Because it has both imaging and focusing functions, it is widely used in optical communication systems, micro-optical systems, medical optical diagnostic instruments, optical copiers, fax machines, scanners and other instruments and equipment.
In optical communication systems, it is one of the basic components of various passive and active devices such as optical fiber connectors, optical fiber couplers, wavelength division multiplexers, optical attenuators, optical isolators, optical filters, optical switches, optical fiber collimators, erbium-doped fiber amplifiers, fiber gratings, integrated optics, etc. It has the characteristics of high coupling efficiency and low insertion loss.
