Stilb

Definition

The Stilb is a CGS unit of luminance, equal to 10,000 candela per square meter. It was part of the centimeter-gram-second system and is still used in some specialized applications, particularly in older scientific literature and certain technical contexts.

History/Origin

The stilb was originally defined in the CGS system as a unit of luminance, named after the Greek word for brightness. It was widely used in early photometry and lighting science before the adoption of SI units became standard in most applications.

Current Use

Still used in some specialized scientific applications, particularly in older technical specifications and certain branches of photometry. While largely replaced by SI units, it occasionally appears in historical contexts and specialized measurement systems.

Lumen per Square Meter Steradian

lm/(m²·sr)

Definition

The Lumen per Square Meter Steradian is a unit of luminance that explicitly shows the relationship between luminous flux, area, and solid angle. It is dimensionally equivalent to candela per square meter and provides insight into the geometric aspects of light measurement.

History/Origin

This unit was developed to emphasize the relationship between luminous flux, surface area, and solid angle in luminance measurements. It provides a more detailed understanding of how light is distributed and measured in three-dimensional space.

Current Use

Used in advanced photometry and lighting calculations where the relationship between flux, area, and solid angle is important. Common in research applications and detailed lighting analysis where understanding the geometric aspects of light distribution is crucial.
