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.

Watt per Square Centimeter Steradian (at 555 nm)

W/(cm²·sr)

Definition

The Watt per Square Centimeter Steradian at 555 nm is a radiometric unit of luminance that measures radiant power per unit area and solid angle at the peak sensitivity wavelength of the human eye. It is used for precise photometric calculations and laser applications.

History/Origin

This unit was developed for applications requiring precise conversion between radiometric and photometric quantities. The 555 nm wavelength corresponds to the peak sensitivity of the human eye, making it ideal for accurate photometric measurements and laser safety calculations.

Current Use

Used in laser safety, precision photometry, and applications requiring exact conversion between radiometric and photometric units. Essential for laser power measurements, optical system design, and safety calculations where precise luminance values are critical.
