A nanocandela (ncd) is a unit of luminous intensity in the International System of Units (SI), equivalent to one billionth of a candela (cd). The candela measures the light emitted by a source in a ...

Various optical systems or geometries can be used to perform light measurements. For instance, the total power [flux] of a light source can be measured in all directions, in a specific direction or ...

Photometric measurements bias the radiant power at each wavelength with a luminosity function, which models human spectral sensitivity, to account for this variation. The photopic sensitivity function ...

The Convention on the International Regulations for Preventing Collisions at Sea (COLREGS) governs the intensity of navigation lights, requiring a minimum intensity in candelas according to a ...

Admesy’s Asteria is a high-speed measurement device suited for luminance, illuminance and flicker measurements. Based on the popular Admesy platform the Asteria is designed for in-line use with ...
