Aspheric biconvex lens

An aspheric biconvex lens is an optical element with two outward-curving (convex) surfaces whose curvature profile is intentionally modified from a perfect sphere (aspheric), allowing it to more precisely refract and focus incoming light. Wavefront modification refers to custom shaping of the lens surfaces to further reduce aberrations and improve the quality of the focused image. Such lenses are commonly used in precision optical systems, including cameras, microscopes, telescopes, and laser optics, to minimize distortions like spherical aberration and achieve higher image sharpness and compact system design. The term "physical refraction of incoming light" summarizes the basic optical function—bending light rays as they pass through media of different refractive indices[1][2][3][5].
