Candela per Square Inch

cd/in²

Definition

The Candela per Square Inch is an imperial unit of luminance, representing the luminous intensity per unit area using the square inch as the area unit. It is used for measuring very bright light sources and small-area displays.

History/Origin

This unit was developed for applications requiring precise measurement of small, bright light sources where square inches provide a more appropriate area reference. It is particularly useful in electronics and display technology where component sizes are measured in inches.

Current Use

Commonly used in electronics manufacturing, small display technology, and precision lighting applications. Essential for measuring LED arrays, small screens, and compact light sources where square inch measurements are standard.

Lumen per Square Centimeter Steradian

lm/(cm²·sr)

Definition

The Lumen per Square Centimeter Steradian is a unit of luminance using square centimeters as the area unit. It is equivalent to 10,000 candela per square meter and is used for measuring high-luminance sources with more manageable numbers.

History/Origin

This unit was developed as a practical alternative to the square meter unit when dealing with high-luminance applications. It provides more convenient numbers for measuring bright light sources and is commonly used in display technology and laser applications.

Current Use

Frequently used in display technology, laser systems, and high-intensity lighting applications. Common in measuring LED displays, plasma screens, and other bright light sources where precise luminance control is essential for performance and safety.
