"Emittance" is a common misspelling or typo for: remittance, remittances, admittance.

Specialty Definition: EMITTANCE

Domain Definition
Aerospace (Symbol E) 1. The radiant flux per unit area emitted by a body. 2. The ratio of the emitted radiant flux per unit area of a sample to that of a black body radiator at the same temperature and under the same conditions. Spectral emittance refers to emittance measured at a specified wavelength. Because of the two common meanings of emittance, it should be defined when used unless the context allows no misinterpretation. (references)
Energy The emissivity of a material, expressed as a fraction. Emittance values range from 0.05 for brightly polished metals to 0.96for flat black paint. (references)
Environment A term for the radiant flux of energy per unit area emitted by a body. (Now obsolete). (references)
Geography Quotient of the flux of radiation emitted by an infinitesimal element of surface containing the point under question, by the area of that element. Source: European Union. (references)
Physics The ratio of the radiant energy (heat) emitted from a surface at a given temperature to the energy emitted by a perfect black body at the same temperature. Source: European Union. (references)
Post & Telecom The power radiated per unit area of a radiating surface. Source: European Union. (references)

Common Expressions: EMITTANCE

Expressions Definition
Beam emittance The beam emittance of a particle accelerator is the amount of spread of the beam as it travels. A low emittance particle beam is a beam which does not spread. (references)

Specialty Expressions: EMITTANCE

Expressions Domain Definition
Directional emittance Aerospace Emittance in a stated direction from a surface. The direction is usually specified as angle from the normal. (references)
Hemispherical emittance Aerospace The ratio of the emissive power of a specimen to that of a black body at the same temperature, considering radiation emitted in all possible directions.Symbol eh, Eh. (references)
Luminous emittance Aerospace The emittance of visible radiation weighted to take into account the different response of the human eye to different wavelengths of light. See luminous efficiency.In photometry, luminous emittance is always used as a property of a self-luminous source, and therefore should be distinguished from luminance. (references)
Microwave Emittance Space Electromagnetic radiation emanating from a body in the microwave band. (references)
Normal emittance Aerospace Emittance in a direction perpendicular to the surface or in a small solid angle whose axial ray is perpendicular to the surface. (references)
Radiant emittance Aerospace See emittance, sense 1. (references)
Radiant emittance Business Radiant power emitted into a full sphere, i.e., 4π sr (steradians), by a unit area of a source, expressed in watts per square meter. Synonym radiant exitance. (references)
Radiant emittance Geography Quotient of the flux of radiation emitted by an infinitesimal element of surface containing the point under question, by the area of that element. Source: European Union. (references)
Radiant emittance Physics The ratio of thermal radiation from the unit area of a surface to the radiation from unit area of a full emitter("black body")at the same temperature. Source: European Union. (references)
Thermal Emittance Space Emittance of radiation by a body not at absolute zero due to the thermal agitation of its molecules. (references)
Total emittance Aerospace = total emissive power. See emittance. (references)
Total hemispherical emittance Geography The emittance of a sample at a given temperature, integrated over all angles of emission. Source: European Union. (references)
