irradiance

Irradiance. Image credit: MIT Also known as radiant flux density, the total energy at all wavelengths falling on a point on a surface from all directions above the surface in a given time. It is measured in watts per square meter (W/m²). See also illuminance.

Irradiance

Irradiance is the power of electromagnetic radiation per unit area (radiative flux) incident on a surface. Radiant emittance or radiant exitance is the power per unit area radiated by a surface. The SI units for all of these quantities are watts per square meter (W/m2), while the cgs units are ergs per square centimeter per second (erg·cm−2·s
