Convert photon flux to watts
WebWatt = J/s is a unit of power. And. What you want is a flux of photons (mol of photons/s or Einstein/s). It means that you need to convert J in E (or mol). It requires the energy of one photon of ... WebIrradiance. 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 −2 ). The CGS unit erg per square centimetre per second (erg⋅cm −2 ⋅s −1) is often used in astronomy. Irradiance is often called intensity, but this term is avoided in radiometry ...
