Preferred Label : actinometer;
IUPAC definition : A chemical system or physical device which determines the number of photons in a beam
integrally or per unit time. This name is commonly applied to devices used in the
ultraviolet and visible wavelength ranges. For example, solutions of iron(III) oxalate
can be used as a chemical actinometer, while bolometers, thermopiles, and photodiodes
are physical devices giving a reading that can be correlated to the number of photons
detected.;
