WebWhile the diameter of conventional SELFOC ® Micro Lens ranged from 1.0mm to 4.0mm for telecommunication devices and from 0.25mm to 2.70mm for imaging devices, the new … WebGradient index (GRIN) lenses are simple planar lenses which continuously bend light rays within the lens until they finally converge on the focal point. This contrasts with conventional lenses , which primarily bend light abruptly when it exits...
WebSELFOC Microlens. Light passing through a gradient-index lens is focused as in a convex lens. SELFOC Microlenses are flat-ended gradient-index lenses. The refractive index … WebThe SELFOC lens utilizes a radial gradient. The index of refraction is highest at the center of the lens and decreases with radial distance from the axis. The following equation describes the refractive index distribution of a SELFOC lens: Equation 1. 𝑁𝑁(𝑟𝑟) = 𝑁𝑁. 0 (1. −. A2 2 r2) This equation shows that the index falls
