Candela per Square Centimeter
cd/cm²
Definition
The Candela per Square Centimeter is a metric unit of luminance, equal to 10,000 candela per square meter. It is commonly used for measuring very bright light sources and high-intensity displays where the standard unit would result in very large numbers.
History/Origin
This unit emerged as a practical alternative to the base SI unit when dealing with high-luminance sources. It provides more manageable numbers when measuring bright displays, laser sources, and intense lighting applications where the square meter unit becomes unwieldy.
Current Use
Frequently used in display technology, laser applications, and high-intensity lighting systems. Common in measuring LED displays, plasma screens, and other bright light sources where precise luminance control is critical for performance and safety.
