luminance measurement

Luminance measurement is conducted by means of a special device called a luminancemetre or nitmeter. It is based on two optical systems, directional and measurement systems, respectively.

The directional system is oriented in such a way that the image coincides with the point to be measured. Once it has been oriented, the light that reaches it is transformed into electric current. Its values are measured in cd/m2.
