What is a Luminance meter?

A luminance meter is a measuring device for measuring luminance, which is a unit of brightness that a person perceives. It measures the brightness of a light source or an object that emits light reflected from the light source. It is mainly used for the development and inspection of lighting equipment and displays. For measurement, an element called a photodiode that emits an electric signal according to the intensity of light is used. There is a luminance meter that can measure by color, and the luminance of each color is measured by separating each of the three primary colors of light and measuring them individually.

Application of Luminance meter

Luminance meters are used in devices that measure the output of a light source, develop and inspect displays, and make non-contact measurements using luminance. By quantitatively evaluating the brightness of lighting, which is the brightness that people perceive, it is possible to set a stable measurement standard. When selecting a luminance meter, it is necessary to consider whether it is compatible with output such as measurement accuracy and color, and whether the attached lens can be focused.
