Grin thermal lens
WebDec 10, 2024 · Rather than the homogenous hunk of glass that makes up a conventional optical lens, a gradient-index (GRIN) optic has a refractive index that varies as a function of position inside the optic; this adds an extra degree of freedom that can simplify the shape of the optic or add extra capabilities. For example, a common type of GRIN lens is a rod … Weblenses of which the surface refraction index has been modified by diffusion techniques based on thermal ion exchange in glass. In particular the aim is the measurement of the variations in focal length of ophtalmic lenses after undergoing a diffusion process. As these variations are extremely small, an interferometric technique is needed.
