Definition
The Nox is a unit of illuminance equal to one-thousandth of a lux, representing very low levels of illumination. It is used for measuring extremely dim light conditions, such as those found in night vision applications, astronomical observations, or specialized scientific measurements.
History/Origin
Developed for measuring very low illumination levels that are below the practical range of the lux. The nox provides a convenient unit for expressing extremely dim light conditions in scientific and technical applications where precision is important.
Current Use
Used in specialized applications requiring measurement of very low light levels, such as night vision technology, astronomical photometry, and scientific research involving extremely dim light sources. It provides a practical scale for quantifying near-threshold illumination conditions.
