Product description
The self-focusing lens (Grin Lens), also known as the gradient-index lens, refers to a cylindrical optical lens whose refractive index distribution gradually changes along the radial direction. It has the functions of focusing and imaging.
Applications
Due to the end-face collimation, coupling, and imaging characteristics of the gradient-index lens, combined with its small cylindrical shape, it can be more conveniently used in a variety of different micro-optical systems. And it has a wide range of applications in the field of integrated optics, such as micro-optical systems, medical optical instruments, optical copiers, fax machines, scanners, and other equipment.
The gradient-index lens is an essential basic component in passive optical communication devices. It is applied to various occasions requiring focusing and collimation functions and is respectively used in optical couplers, collimators, optical isolators, optical switches, lasers, etc.
Main Features
- Small volume
- The cylindrical shape makes it easier to assemble
Main Applications
- Optical collimator
- Optical isolator
- DWDM device
