Gradient-index (GRIN) optics 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 … See more The lens of the eye is the most obvious example of gradient-index optics in nature. In the human eye, the refractive index of the lens varies from approximately 1.406 in the central layers down to 1.386 in less dense layers of the … See more In 1854, J C Maxwell suggested a lens whose refractive index distribution would allow for every region of space to be sharply imaged. Known as the Maxwell fisheye lens, it involves a spherical index function and would be expected to be spherical in shape … See more • Graded-index fiber See more The ability of GRIN lenses to have flat surfaces simplifies the mounting of the lens, which makes them useful where many very small … See more GRIN lenses are made by several techniques: • Neutron irradiation – Boron-rich glass is bombarded with neutrons to cause a change in the boron concentration, and thus the refractive index of the lens. • Chemical vapour deposition See more An inhomogeneous gradient-index lens possesses a refractive index whose change follows the function $${\displaystyle n=f(x,y,z)}$$ of the coordinates of the region of interest in … See more
