WebFeb 5, 2024 · Understand photometers that measure lux and foot-candles. These are units that describe the intensity of light on a surface, or illuminance. Photometers that measure this are usually what people are looking for when they want to set up a photo shoot, or test whether a room is too bright or too dim. WebThe sample is vaporized in the flame, and atomized by a combination of heat and the action of a reducing gas. The atoms are excited into higher electronic states by the heat, and as they revert to the ground state they emit photons, which are measured by the detector. The layout of a flame photometer is shown in Figure 2.
