photometric equipment

Photocells of various kinds used to measure photometric quantities; i.e., intensity, luminance and illuminance. Meter readings are used to express illuminance and, by calibration, to measure intensity and luminance. Other photometric quantities requiring measurement include transmission and reflection densities in photography, the reflectance of a mirror or a screen and the transmittance of an optical instrument.
