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.
Understanding the Aspherical Lens in Photography (Asph Lens)
网页Aspherical lenses are curved outwards on their rear element so that they can better direct light rays into a single focal point. These counter-curves help correct spherical aberration, creating sharper images.
What Are Aspheric Lenses & How Do They Work? - Vision Center
网页2024年5月3日 · Aspheric means “non-spherical,” so there is less of a bulge or curve. Conventional lenses have a spherical curvature on the front of the lens (like a basketball). On the other hand, aspheric lenses are smoother and flatter, reducing distortion when wearing glasses.
Aspherical Definition & Meaning - Merriam-Webster
网页The meaning of ASPHERIC is departing slightly from the spherical form especially in order to correct for spherical aberration. How to use aspheric in a sentence.
ASPHERICAL Definition & Meaning - Dictionary.com
网页Aspherical definition: (of a reflecting surface or lens) deviating slightly from a perfectly spherical 1 shape and relatively free from aberrations.. See examples of ASPHERICAL used in a sentence.
All About Aspheric Lenses - Edmund Optics
网页An aspheric lens can be designed to minimize aberration by adjusting the conic constant and aspheric coefficients of the curved surface of the lens. Figure 1 shows a spherical lens with significant spherical aberration compared to an aspheric lens with practically no spherical aberration.
What Is an Aspherical Lens — All You Should Know

Aspherical lens element: What is it and how does it work?
网页2014年11月2日 · The aspherical lens element has helped to improve the optical quality of camera lenses in recent years. You may have seen ‘Asph’ or ‘Aspheric’ marked on a camera lens or in lens specifications. It’s now widely regarded as a mark of excellence.
A Comprehensive Guide to Aspheric Lenses — Firebird Optics
网页2023年2月5日 · Aspheric lenses are optical lenses that deviate from the ideal spherical shape. They are used to correct various types of aberrations, such as spherical aberrations, distortion, and field curvature, which are often present in traditional spherical lenses.
Aspheric Lenses: Design Considerations | Optics - Photonics
网页aspheric lens. An aspheric lens is a type of lens whose surface profiles deviate from the traditional spherical shape. Unlike spherical lenses, which have a constant curvature across their surfaces, aspheric lenses feature varying curvatures, allowing for improved optical performance and correction of aberrations.
