PRODUCT OVERVIEW
Introduction
Aspheric lenses are optical lenses with one or more surfaces whose curvature varies continuously from the center toward the edge rather than following a constant spherical radius. This controlled surface profile allows light rays passing through different regions of the lens to be directed more accurately toward the intended focus, reducing spherical aberration and improving optical performance.
By incorporating aberration correction directly into the lens surface, aspheric lenses can often replace multiple spherical elements within an optical system. This helps reduce component count, system length, and alignment complexity while supporting demanding imaging, collimation, and focusing requirements.
