Graded index optics
WebGradient-index lenses are lenses not requiring curved surfaces, because instead they employ a radially varying refractive index. They provide compact and possibly cheap solutions for many applications. WebJan 20, 2024 · The accuracies of several numerical ray-tracing methods for graded-index optical media are investigated. Tracing is done by numerically solving the ray equation for the classical Luneburg lens.
