cathode-ray tube envelope

Envelopes for cathode-ray tubes are made by blowing glass in the same manner as light bulbs. They have a fairly flat end face to carry the phosphor material applied internally.

color blocking -> contact blocking

Also called color blocking. The formation of a block by making optical contact between a number of optical elements and a large optical flat.

color comparator

1. A device used in chemistry to compare the colors of solutions held in flat-bottomed tubes and viewed along the length of the tube. Often a solid glass plunger is moved along one of the tubes to...

constant angle fringes -> Haidinger fringes

Also known as constant angle or constant deviation fringes. The interference fringes observed with dense flat plates near normal incidence. The fringes of the Fabry-Perot interferometer are Haidinger...

constant deviation fringes -> Haidinger fringes

contact blocking

Also called color blocking. The formation of a block by making optical contact between a number of optical elements and a large optical flat.

cosine collector

Translucent collector developed to compensate for the partial blocking of a flat surface's collection angle that normally occurs in spectroradiometry. The device samples radiant flux according to the...

coverslip

A coverslip, also known as a cover glass or cover slip, is a thin and flat piece of transparent material typically made of glass or plastic. It is used in microscopy to cover a specimen mounted on a...

curvature

The measure of departure from a flat surface, as applied to lenses; the reciprocal of radius. Applies to any surface, including lenses, mirrors and image surfaces.

curvature of field

A lens aberration that causes a flat object surface to be imaged onto a curved surface rather than a plane.

custom lapping and polishing services

Custom lapping and polishing services involve specialized processes used to improve the surface finish and dimensional accuracy of components to meet specific requirements or standards. These...
