Lumen per Square Centimeter

lm/cm²

Definition

The Lumen per Square Centimeter is a unit of illuminance equal to 10,000 lux, representing the luminous flux per unit area using the centimeter as the area unit. It is used for measuring very high levels of illumination, particularly in concentrated light sources or small area applications.

History/Origin

Developed as part of the CGS system where smaller area units were commonly used. It provides a convenient way to express high illumination values without using very large numbers, particularly useful in scientific and technical applications.

Current Use

Used in specialized applications requiring measurement of very high illumination levels, such as laser technology, concentrated light sources, or scientific research involving intense light fields. It provides a practical scale for quantifying high-intensity illumination.
