Graded index fiber
WebMulti-mode optical fiber has a core diameter that is much larger than the wavelength being carried. The large core allows for high numeric apertures for superior light gathering compared to single mode fibers. We offer graded index, step index, and power delivery multimode fibers to meet most bulk light transport requirements. WebStandard graded-index fibers typically have a core diameter of 50 or 62.5 µm and a cladding diameter of 125 µm. See step-index fiber and dispersion-shifted fiber . …

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. WebGraded-index (GI) fibre reduces multimode dispersion by grading the refractive index of the core so that it smoothly tapers between the core centre and the cladding. …
