WebThe distal portion of the optic vesicle makes contact with the overlying surface ectoderm, resulting in the specification of the lens ectoderm (preplacodal stage). This interaction leads to invagination of the lens placode and distal optic vesicle resulting in formation of a bilayered optic cup (Figs. 3.1 B and 3.3 ). WebGradient-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 …
