WebApr 13, 2024 · Plano-Convex & Biconvex Lenses. As their name implies, both plano-convex and biconvex lenses have either one or two surfaces with positive spherical contours. Regardless of design, the thickness at the edge of the lens is always less than the thickness at the center. These lenses are used to focus light to a pre-defined point based on the ... Web5.1. Ray-tracing an Aspheric Lens To test the intersection of a ray and the aspheric surface, we use a bracketing-based root-finding method (either the bisection or the false position method). The explicit lens definition (Eq. (1)) is incon-venient for this process, and we instead reformulate it to an implicit representation. Eq.
