About These Units

Apostilb (asb)

The apostilb (asb) equals 1/π cd/m² ≈ 0.318 nits. Represents the luminance of a perfect diffuser illuminated by 1 lux. Also called blondel. One apostilb ≈ 0.0929 foot-lamberts. Useful in theoretical calculations involving diffuse reflection.

Candela per Square Millimeter (cd/mm²)

A candela per square millimeter (cd/mm²) equals 1,000,000 nits. Measures extremely intense sources: laser output facets, concentrated LED dies, and arc lamp electrodes. A high-power LED die can exceed 100 cd/mm². Used in optical engineering calculations.
