Applications
GOSSEN’s precision luminance meters are used for distance and contact
measurements for all types of light sources. For the purpose of adhering
to applicable norms, this allows for testing of minimum and maximum lu-
minosity, assurance of quality requirements specified for products with
displays or lamps, ascertainment of maintenance requirements due to aging,
and optimization of illumination uniformity. Scope of validity, terminology,
responsibilities, requirements and practical guidelines are set forth to a great
extent in the standards.
Luminance (abbreviation: L, unit of measure: cd per m²)
indicates the brightness impression perceived by the eye when positioned in
front of a back-lighted or illuminated surface. It describes the physiological
effect of light on the eye, and is used as a planning factor for outdoor lighting.
