Exempel på hur man kan använda ASPHERIC i en mening

• In lens systems, aberrations can be minimized using combinations of convex and concave lenses, or by using aspheric lenses or aplanatic lenses.
• A Schmidt corrector plate is an aspheric lens which corrects the spherical aberration introduced by the spherical primary mirror of the Schmidt or Schmidt–Cassegrain telescope designs.
• A slit lamp biomicroscopic examination along with an appropriate aspheric focusing lens (+66D, +78D or +90D) is required for a detailed stereoscopic view of the optic disc and structures inside the eye.
• Schmidt realized that he could eliminate the spherical aberration by placing a thin, very weakly curved aspheric lens (now called the "Schmidt corrector plate") at the same center of curvature as the apertured diaphragm.
• However, where the Schmidt uses an aspheric corrector at the entrance pupil, Maksutov's telescope uses a deeply curved full diameter negative meniscus lens (a "meniscus corrector shell").
• The ECE regulations in use throughout most of the world except North America permit the driver-side mirror to have a planar, convex, or aspheric surface; an aspheric section is often combined with a larger convex section, and the two sections are separated by a visible line to alert the driver to the two sections' different perspective shifts.
• Mangin mirrors are also used in null correctors, which are used to fabricate large aspheric mirrors.
• In some cases, more aesthetic aspheric lens designs can be fitted, reducing Scotoma associated with lenticulars.
• Designs followed using other optical configurations including Schmidt configuration and solid catadioptric designs (made from a single glass cylinder with a maksutov or aspheric form polished into the front face and the back spherical surface silvered to make the "mirror").
