WebIrradiance (or flux density) is a term of radiometry and is defined as the radiant flux received by some surface per unit area. In the SI system, it is specified in units of W/m 2 (watts per square meter). Irradiance may be applied to light or other kinds of radiation.

WebApr 1, 2024 · The new proposed method requires that the irradiance to be accurately measured across the water surface, which needs a precise apparatus that is not always available. Furthermore, the magnitude of the fluence rate of a single UV-LED 13 cm above the water, was one-tenth of that of usually seen for UV lamps. Web4.3.1 Effect of laser fluence and number of shots. Different laser fluences were used to determine the energy range needed for gold melting in the case of rough substrates (Ra > 0.15 μm corresponding to gold thickness higher than 0.75 μm) commonly used in industry. For small fluences (lower than 400 mJ/cm 2 ), laser impacts were not observed.

In radiometry, irradiance is the radiant flux received by a surface per unit area. The SI unit of irradiance is the watt per square metre (W⋅m ). The CGS unit erg per square centimetre per second (erg⋅cm ⋅s ) is often used in astronomy. Irradiance is often called intensity, but this term is avoided in radiometry where such usage leads to confusion with radiant intensity. In astrophysics, irradiance is called radiant flux.
