Emittance may
refer to: Beam
emittance, the area
occupied by a beam in a position-and-momentum
phase space Radiant emittance, the
radiant flux emitted...
-
spread of the
coordinates on this plot are the
emittance. As such, a beam will have
three emittances, one
along each axis,
which can be
described independently...
- perception. Similarly,
luminous emittance is the
luminous flux per unit area
emitted from a surface.
Luminous emittance is also
known as
luminous exitance...
-
Thermal emittance or
thermal emissivity ( ε {\displaystyle \varepsilon } ) is the
ratio of the
radiant emittance of heat of a
specific object or surface...
-
surface per unit area. This is the
emitted component of radiosity. "Radiant
emittance" is an old term for this quantity. This is
sometimes also confusingly...
-
transverse emittance with MTE, it is
sometimes useful to
write the
equation in
terms of a new
quantity called the
thermal emittance. The
thermal emittance is...
- terms,
emittance and
thermal emittance, are used to
describe thermal radiation measurements on
complex surfaces such as
insulation products.
Emittance of...
-
exitance or
radiant emittance is the
radiant flux
emitted by a
surface per unit area,
whereas spectral exitance or
spectral emittance is the
radiant exitance...
- is the
variation of
reflectance or
emittance of a
material with
respect to
wavelengths (i.e., reflectance/
emittance as a
function of wavelength). The spectral...
-
building surfaces, such as
paint coatings,
brick and
concrete have high
emittances of up to 0.96. They
radiate heat into the sky to p****ively cool buildings...
