Definition of radiance in English English dictionary: the flux of radiation emitted per unit solid angle in a given direction by a unit area of a source; the quality of being radiant, shining, bright or splendid; brilliant or sparkling luster; {i} brilliance, glowing quality; warmth, joy, happiness; amount of radiation per unit solid angle (Optics); the amount of electromagnetic radiation leaving or arriving at a point on a surface; Optical power per unit solid angle per unit area from source; Electromagnetic energy flux, the amount of energy traveling at some point x in a specified direction , per unit time per unit area perpendicular to the direction per unit solid angle for a specified wavelength denoted by; A measure of the energy radiated by the object together with the frequency distribution of that radiation; The radiation passing through a point in a specific direction, expressed in SI units of watts per steradian per square meter In the Radiance system, only visible radiation is considered, but units of radiance and irradiance are still used, which are divided into separate components for the red, green, and blue spectral ranges (Compare to luminance ); Brightness; the radiant energy per unit solid angle and per unit projected area of a radiating surface; Irradiance per unit solid angle (W/m2 - steradian); Radiance is a measure of radiometric flux density per unit solid angle Radiance is typically expressed in W/cm2/sr (watts per square centimeter per steradian); the quality of being bright and sending out rays of light the amount of electromagnetic radiation leaving or arriving at a point on a surface an attractive combination of good health and happiness; "the radiance of her countenance; A measure of the amount of electromagnetic radiation leaving a point on the surface More precisely, it is the rate at which light energy is emitted in a particular direction per unit of projected surface area The projected surface area is the projection of the surface onto the plane perpendicular to the direction of radiation It is found by multiplying the surface area by , where is the angle of the radiated light to the surface normal; The quality of being radiant; brilliancy; effulgence; vivid brightness; as, the radiance of the sun; Measure of the energy radiated by an object In general, radiance is a function of viewing angle and spectral wavelength and is expressed as energy per solid angle; The radiation energy per unit time coming from a specific direction and passing through a unit area perpendicular to the direction; Radiance is a glowing light shining from something. The dim bulb of the bedside lamp cast a soft radiance over his face; the quality of being bright and sending out rays of light; The radiant flux as Watts per unit soled angle per unit of projected area of the source in units described as watts/m2/steradian Steradain (sr) is the unit solid angular measurement, being the subtended surface area of a sphere divided by the square of the sphere radius There are four steradians in a sphere For instance the solid angle subtended by a cone of a half angle is 2 (1-cosine) steradians; In radiometry, a measure of the intrinsic radiant intensity emitted by a radiator in a given direction; Radiance is great happiness which shows in someone's face and makes them look very attractive. She has the vigour and radiance of someone young enough to be her grand-daughter; an attractive combination of good health and happiness; "the radiance of her countenance"
