Radiance and spectral radiance are measures of the quantity of radiation that passes through or is emitted from a surface and falls within a given solid angle in a specified direction. They are used in radiometry to characterize diffuse emission and reflection of electromagnetic radiation. In astrophysics, radiance is also used to quantify emission of neutrinos and other particles. The SI unit of radiance is watts per steradian per square metre (W·sr−1·m−2), while that of spectral radiance is W·sr−1·m−2·Hz−1 or W·sr−1·m−3 depending on if the spectrum is a function of frequency or of wavelength.

Famous quotes containing the word radiance:
“Surrealism ... is the forbidden flame of the proletariat embracing the insurrectional dawnenabling us to rediscover at last the revolutionary moment: the radiance of the workers councils as a life profoundly adored by those we love.”
—Manifesto of the Arab Surrealist Movement (1975)
if you care to call those spasmodic
Tricks of radiance miracles. The waits begun again,
The long wait for the angel,
For that rare, random descent.”
—Sylvia Plath (19321963)
“The complete life, the perfect pattern, includes old age as well as youth and maturity. The beauty of the morning and the radiance of noon are good, but it would be a very silly person who drew the curtains and turned on the light in order to shut out the tranquillity of the evening. Old age has its pleasures, which, though different, are not less than the pleasures of youth.”
—W. Somerset Maugham (18741965)
