The stilb (sb) is the CGS unit of luminance for objects that are not self-luminous.
The name was coined by the French physicist André Blondel around 1920.
[1] It comes from the Greek word stilbein (στίλβειν), meaning 'to glitter'.
In North America self-explanatory terms such as candle per square inch and candle per square meter were more common.
The current national standard for SI in the United States discourages the use of the stilb.
