Aspheric lens - Wikipedia
网页An aspheric lens or asphere (often labeled ASPH on eye pieces) is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.
所有关于非球面透镜 | 爱特蒙特光学 - Edmund Optics
网页球面像差是由使用球面表面来聚焦或对准光线而产生的。 因此，换句话说，所有的球面表面，无论是否存在任何的测量误差和制造误差，都会出现球差，因此，它们都会需要一个不是球面的、或非球面的表面，对其进行校正。 通过对圆锥常数和非球面系数进行调整，任何的非球面透镜都可以得到优化，以最大限度地减小像差。 例如，请参考图1，其展示了一个带有显著球面像差的球面透镜，以及一个几乎没有任何球差的非球面透镜。 球透镜中所出现的 …
Understanding the Aspherical Lens in Photography (Asph Lens)
网页Aspherical lenses are used primarily in high-end optics to create sharper images and reduce or eliminate certain optical imperfections (i.e. chromatic aberrations, field curvature, etc.). They also allow manufacturers to create smaller and lighter lenses since they reduce the need for numerous lens elements and lens groups.
All About Aspheric Lenses - Edmund Optics
网页The term asphere encompasses any lens with surfaces that are not portions of a sphere. However, when we use the term here we are specifically talking about the subset of aspheres that are rotationally symmetric optics with a radius of curvature that varies radially from the center of the lens.

What Are Aspherical Lens Elements? - PetaPixel
网页2019年9月7日 · Aspheric lens elements have surfaces that aren’t portions of a sphere, and this more complicated shape focuses light better than a simple lens, reducing various types of aberrations.
网页A spherical lens is defined by a single radius of curvature and can be ground and polished by a tool larger than the component, working the entire sur-face at the same time. In contrast, the continuously variable radius of cur-vature of an aspheric lens requires sub-aperture polishing with tools that are small enough to create different.
