Custom Aspheric Lens
An aspheric lens is an optical element with a complex curved surface profile. Its surface curvature is not a simple sphere, but is designed through precise mathematical equations (such as conic sections plus higher-order polynomials). This unique design allows it to effectively overcome the inherent spherical aberration of traditional spherical lenses — the aberration in which parallel light cannot converge to the same point after refraction by the lens.
