Astronomical Photometry: A Guide
1.2.1 General definitions We now discuss four fundamental quantities in
radiometry: radiant flux, radiant intensity, irradiance and radiance. The
corresponding quantities in photometry are distinguished by the root "lumi-" in
place of "radi-": ...

Total radiant flux : It is the total energy of radiation emitted by a source per unit
time. This radiation contains components of various wavelengths extending even
beyond the 'visible range. The SI unit of total radiant flux of a source is watt.

The flux can be arriving at the surface in which case the radiant flux density is
referred to as irradiance. Irradiance is defined as E A =d d Φ , (4.9) where Φ is
the radiant flux arriving at the infinitesimal area dA. Since irradiance is the radiant
flux ...

Introduction to Mathematical Modeling of Crop Growth
Among the common terms that will be used in this book are radiant flux, radiant
flux density, irradiance and radiant emittance. Radiant flux is the amount of

Encyclopedia of Optical Engineering
Radiant flux or power <P is the rate at which radiant energy is transferred from
one region of space to another by the electromagnetic radiation field: <P = dQ/dt
in units of watts (W). Radiant exitance M is the
radiant flux or power d0 leaving
the ...

Interior Textiles: Fabrics, Application, and Historic Style
All carpet flammability tests are based on a critical radiant flux (CRF), calculated
from the distance of flame spread converted into watts per square centimeter (
watts/sq. cm, or watts/cm2), indicating the critical or threshold level to sustain ...

It is defined as Fv 1⁄4 Km Z l Fe;lVðlÞdl ðA2:2:3Þ where F e,l is the spectral
concentration of radiant flux as a function of wavelength l. The term, luminous flux
, is often used in the meaning of total luminous flux (see A2.2.3.8) in photometry.
