Grin optical fiber
WebGRIN lenses can be used for a wide range of applications – for example: fiber collimators, where a GRIN lens may be fused to a fiber end; fiber-to-fiber coupling; mode field adapters; focusing applications, e.g. optical … The ability of GRIN lenses to have flat surfaces simplifies the mounting of the lens, which makes them useful where many very small lenses need to be mounted together, such as in photocopiers and scanners. The flat surface also allows a GRIN lens to be easily optically aligned to a fiber, to produce collimated output, making it applicable for endoscopy as well as for in vivo calcium imaging and optogenetic stimulation in brain.
