About this document
Understanding Fiber Optic Lenses by farhan9125 is a document available to read on EtoBox.
The document discusses different types of lenses used in fiber optic communications. It describes thin lenses and how their focal length is determined based on the radii of curvature. Cylindrical lenses are used to collimate light from a line source so the rays emerge parallel to the lens axis. Graded index rod lenses have a refractive index that varies radially, causing ray paths inside to be sinusoidal. They are commonly used to collimate or focus light beams coupling between fibers.
