Spectral photon irradiance

Term · Chemistry · MLC-T-CHM-011135

The radiant flux of photons incident on a surface per unit area, per unit wavelength interval. It describes the number of photons arriving at a surface at a specific wavelength. This quantity is expressed in units of photons per second per square meter per nanometer (photons s-1 m-2 nm-1).
