WebJan 11, 2024 · Irradiance is not a vector, it is a scalar. It is true that the Wiki entry mentions the Poynting vector, but note that only its modulus is present. The "cos" menas that, for the same source of light, the irradiance on a surface placed at a slanting angle to the source, the irradiance is less than if the surface faces the source. WebIrradiance calibrations (µW/cm2) are normally performed on a system with a fibre-optic cable and a cosine corrector or integrating sphere. The irradiance calibrations can be performed over 3 different wavelength ranges, UV (200-400 nm), VIS (360-1100 nm) and NIR (1100-2500 nm).
