-
Lambert is suited mainly for self-luminous or diffusely reflecting surfaces, affecting interpretation
-
Conversion application is context-dependent and may not suit strict SI regulatory environments
Frequently Asked Questions
-
What does candela per square centimeter measure?
-
It measures the luminous intensity per unit area emitted by small, high-intensity surfaces, such as display elements.
-
How is lambert [L] used in luminance measurement?
-
Lambert is a CGS unit used for self-luminous or diffusely reflecting surfaces, commonly in optical and photographic contexts.
-
Why convert between candela per square centimeter and lambert?
-
Converting helps translate luminance values across SI-derived and CGS units, facilitating comparison in various technical and historical analyses.
