How to Choose an Aspheric Intraocular Lens - American ...

These lenses are designed to eliminate the positive spherical aberration added by traditional IOLs to the pseudophakic visual axis. But IOL makers took different roads to asphericity, yielding a collection of aspheric lenses that variously seek to neutralize all, some or none of the visual system's naturally occurring corneal spherical ...

Synopsys' CODE V Enhances Aspheric Lens System Design

Aspheric surface shapes are used to help reduce or eliminate imperfect or blurred images in optical systems. While surfaces with spherical shapes are easier to make, many more spherical surfaces are generally needed to reduce image blurring compared to aspheric surfaces.

Aspheric Lenses - Binoculars - Cloudy Nights

Jul 26, 2004 · A common aberration of lenses is spherical aberration. In a system with spherical aberration, the light traveling through the edge of the lenses will focus at a different distance behind the lens than light through the edge. For slow systems, it is not hard to design a system with all spherical surfaces that is well corrected for spherical ...

Spherical aberration occurs in common singlet lenses, which results in an image that appears distorted, aspheric lenses correct spherical aberration. An aspheric lens surface is designed non-spherical, which allows a single component lens to collimate or focus highly divergent rays potentially replacing a -lens system.

While individual spherical lenses can refract light at only small angles before spherical aberration is introduced, aspheric lenses are designed with curved surfaces that deviate from a sphere. This deviation is designed to eliminate spherical aberrations when light is refracted at large angles.

Spherical coordinate system - Wikipedia

In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its polar angle measured from a fixed zenith direction, and the azimuth angle of its orthogonal projection on a reference plane that passes through the origin and is orthogonal to the ...

In this paper, mixed-surface-type optical system is defined as the optical system comprised of various types of surfaces, including spherical, aspheric, and freeform surfaces. A general point-by-point design method for mixed-surface-type systems is proposed. In detail, methods for spherical system design and optical power assignment are proposed during the point-by-point design process.

Spherical aberration - Wikipedia

In lens systems, the effect can be minimized using special combinations of convex and concave lenses, as well as using aspheric lenses or aplanatic lenses. Such lens systems are usually designed by numerical ray tracing. For simple designs one can sometimes calculate parameters that minimize spherical aberration.
