Clear All Filters x Visible x C x
calorescence

The production of visible light by infrared radiation whereby the light is produced by heat and not by any direct change in wavelength; the transformation is indirect.

cathode-ray oscilloscope -> oscilloscope

A system in which a supplied signal causes the deflection of the electron beam in a cathode-ray tube, thus forming a visible trace on the phosphor screen of the tube and providing for examination of...

chromatic aberration

Chromatic aberration is an optical phenomenon that occurs when different wavelengths (colors) of light are refracted by a lens or optical system, leading to a failure to focus all colors to the same...

chromatic difference of magnification -> chromatic aberration

cobalt glass

Glass that transmits near-ultraviolet radiation but is opaque in the visible region. Also known as woods glass.

cold mirror

A mirror whose coating serves to reflect visible radiation while transmitting the infrared.

color center

A color center, in the context of materials science and condensed matter physics, refers to a specific type of crystallographic defect in a crystalline structure that introduces color to the...

color filter -> optical filter

An optical filter is a device that selectively transmits or blocks specific wavelengths, or colors, of light. Optical filters are used to control the spectral content of light in various...

color-translating microscope

A type of compound microscope that uses three visible wavelengths to translate details produced by invisible radiation.

contact fluorography

A fluorographic method whereby the sensitive photographic medium is pressed against a fluorescent screen to form a visible image.

cyanometry

The analysis of light in the blue region of the visible spectrum.
