8. Instruments

Only the main types of instrument used in radiometry (energy system) or photometry (light system) are described here.

8.1 Photometry bench, intensity measurements

This equipment is part of the laboratory's basic set-up. The bench makes it possible to arrange source, receivers and detector at known distances, and to use Bouguer's law to obtain continuous gradation of the excitation level. Figures 10 a and b show an example of its implementation for measuring the luminous intensity I _x of a source S _x...
