Lambert
Germanic family name
Lambert is a unit of luminance in the centimeter-gram-second system, measuring the brightness of a surface that emits or reflects light.
Named after German mathematician Johann Heinrich Lambert, it equals the luminance of a perfectly diffusing surface emitting one lumen per square centimeter.
Though largely replaced by SI units like candelas per square meter in modern usage, it still appears in older technical literature and specialized optics contexts.
