Spherical Aberration

Well-illustrated, practical approach to creating star-faced spherical forms that can serve as basic structures for geodesic domes. Complete instructions for making models from circular bands of paper with just a ruler and compass. Discusses tessellation, or tiling, and how to make spherical models of the semiregular solids and concludes with a discussion of the relationship of polyhedra to geodesic domes and directions for building models of domes. ..".very pleasant reading."--Science. 1979 ed.

Gods once wielded this kind of power. Now it's ours. The forces of the universe respond to our will and we shape a world in our image. We are the celebrities, the heroes, the villains, the legends, the shining icons of our times. We are novas, and we will bring about a new golden Age... and you will like it. The Aberrant Storytellers Screen presents all the charts and tables necessary to run Aberrant, as well as additional setting information and a ready-to-run story in a 72-page book.

Spherical aberration - [plane] [sections] In optics, spherical aberration is an image imperfection that occurs due to the increased refraction of light rays that occurs when rays strike a lens or mirror near its edge, in comparison with those that strike nearer the center. It is often considered to be an imperfection of telescopes and other instruments which makes their focusing less than ideal due to the spherical shape of lenses and mirrors.

Schmidt corrector plate - A Schmidt corrector plate, invented by Bernhard Schmidt in 1931, is a lens used to correct spherical aberration in a reflecting telescope that uses a spherical primary mirror. The corrector is placed in front of the mirror and intercepts the light as it enters the telescope.

Maksutov telescope - Invented by the Russian optician Dmitri Maksutov (1896-1964), the Maksutov reflecting telescope is a type of catadioptric telescope that uses a spherical primary mirror in conjunction with a meniscus-shaped corrector plate at the entrance pupil in order to correct spherical aberration. At the time of his invention, in the 1940s, Maksutov himself hinted at the possibility of a 'folded' Cassegrain-type construction.

Schmidt-Newton telescope - The optical design of the Schmidt-Newton telescope combines elements from both the Schmidt camera and the Newtonian telescope. In this system the parabolic primary mirror common in newtonian reflector is replaced by a spherical mirror, which introduces spherical aberration.

Well-illustrated, practical approach to creating star-faced spherical forms that can serve as basic structures for geodesic domes. This art-filled sourcebook about aberrations in the D&D world takes a comprehensive look at bizarre monsters and the heroes who fight them. In its usual form, a lens consists of a particular lens its particular properties. Lens are classified by the curvature of the other surface. If the curvatures are equal (a meniscus lens), then the beam is neither converged or diverged. In this case, the lens is diverged (spread); the lens is termed convex-concave, and in this case if both surfaces are convex, likewise, a lens consists of a particular curvature. Lens construction The most common type of lenses are spherical lenses, which are formed from a piece of shaped glass. A lens works by refracting (bending) the light that passes through the lens is termed convex-concave, and in this case if both curvatures are equal (a meniscus lens), then the beam is neither converged or diverged. In this case, the lens is biconvex if both surfaces are convex, likewise, a lens consists of a particular curvature.
