  • Patent number: 11340449
    Abstract: A method for designing an optical lens with unequal thickness, comprising the steps of: (1) establishing a lens model in an optical software; (2) simulating a beam of incident light, and observing whether the incident light and the exit light are parallel; (3) if the incident light and the exit light are parallel, recording the curvatures and thicknesses of the incident surface and the exit surface of the lens model, and preliminarily preparing a lens; if the incident light and the exit light are unparallel, adjusting the thickness between the incident surface and the exit surface of the lens model until the incident light and the exit light are parallel, then recording the curvatures and thicknesses of the incident surface and the exit surface, and then preliminarily preparing a lens; (4) verifying whether the prepared lens is qualified, and if it is unqualified, returning to step (2).
