How does mass photometry work
WebApr 6, 2024 · The modern photometer meaning 'is the radiant power of every wavelength', measured by a luminosity function as per the human's sensitivity to brightness. Photometry is the science behind the measurement of light, which is perceived in terms of brightness to the human eye. It should not be confused with radiometry which refers to the … WebHistory. Before electronic light sensitive elements were developed, photometry was done by estimation by the eye. The relative luminous flux of a source was compared with a standard source. The photometer is …
