Product Introduction
Grin lens is a cylindrical lens in which the refractive index distribution within the lens gradually decreases radially. It has the function of focusing and imaging. It is the branch of optics covering optical effects produced by a gradient of the refractive index of a material. Such gradual variation can be used to produce lenses with flat surfaces, or lenses that do not have the aberrations typical of traditional spherical lenses. Gradient-index lenses may have a refraction gradient that is spherical, axial, or radial.
Since Grin lens (G lens) optical lenses have end-face focusing and imaging properties, combined with their cylindrical, compact shape, they can be used more conveniently in a variety of miniature optical systems. The self-focusing collimating Grin lens (G lens) optical lenses are usually used in the connection between optical fibers and optical fibers in optical passive devices. Grin lens Optical lenses are indispensable basic components in optical communication as passive devices.
Grin lens (G lens) Optical lenses are used in various applications that require focusing and collimation functions, such as optical couplers, collimators, optical isolators, optical switches, and lasers.
Grin lens (G lens) Optical lenses have widespread applications in fields such as micro-optical systems, medical optical instruments, optical copiers, fax machines, scanners, and other integrated optics devices.
Grin lens (G lens) Optical lenses systems should be stored in a dry environment. For short term storage, the plastic box or foam packing in which optical lenses are shipped will provide adequate storage.
