An aspheric biconvex lens. 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.
A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A simple lens consists of a single ... An aspheric biconvex lens.
In lens systems, aberrations can be minimized using combinations of convex and concave lenses, or by using aspheric lenses or aplanatic lenses. Lens systems with aberration correction are usually designed by numerical ray tracing. For simple designs, one can sometimes analytically calculate parameters that minimize spherical aberration.
The hood of the lens is fixed and the front element protrudes extensively, forcing the lens cap to take an unconventional shape, covering the entire hood. This also does not allow the placing of a filter in the front. The lens contains one glass aspherical element and one hybrid aspherical element. [1]
An atoric lens design refers to a lens with a more complex aspheric lens design. An atoric lens design can address errors over more corners of the lens, not just the horizontal and vertical axis. A toric lens is designed to compensate for the astigmatism of a patient's eye. Even though this lens is technically "aspheric", the terms "aspheric ...
