Aspheric lenses are more expensive to manufacture than are spherical lenses, but for high performance optics the benefits are significant. They also are a good option where a small footprint system is required as the aspheric lens lends itself well to compact assemblies.

Aspheric lenses are optical lenses with non-spherical surfaces (aspherical surfaces), meaning they have a changing curvature across the lens rather than a constant curvature, as seen in spherical lenses.  Because aspheric lenses contain controlled variations in curvature across the surface of the lens, they correct for the optical aberrations that occur with spherical lenses. Removing these aberrations has several important benefits:

Aspheric lensesvs spherical

An aspheric lens is an optical lens with a non spherical surface profile; its surfaces are not portions of a sphere or cylinder. There are many types of custom aspheric lenses with various geometries. Unlike spheric lenses, they do not have a constant radius of curvature. They are designed to eliminate almost all spherical aberration, and by light focused to a small point they drastically decrease the amount of blur and so improve image quality. Using aspheric lenses typically results in more compact assemblies as there are fewer aberrations to be corrected for. As an aspheric lens manufacturer, Avantier manufactures a wide variety of custom aspheric lenses solutions for applications from smartphones to lasers and fiber optics, from research and industry to medicine.

Types of Aspheric Lens An aspheric lens may have any of a number of geometries. Most of them are rotationally symmetric but have a more complex front surface. Unlike a spherical lens, the curvature changes with the distance from the optical axis. Another way of putting this would be to say that the radius of curvature varies radially from the center of the lens.  Typically, the further from the optic axis, the weaker the curvature. A lens that does not have these symmetries is typically called a free-form optic.Aspheric lenses are defined by their surface profile (sag of the surface parallel to the optical axis) or by means of orthogonal coefficients Qbfs and Qcon. Qbfs quantifies the RMS slope departure of your aspheric lens from a best fit sphere,  and Qcon  quantifies the sag departure from a base conic.

By integrating controlled variations in curvature, optical engineers can utilize aspheric lenses to improve systems’ image qualities, create more compact and lightweight designs, and increase design flexibility.
