Measuring the average intensity of the visible radiation emitted from an LED is a critical issue, not just for developers of electro-optical instrumentation and photonics measuring devices, but also ...

The measurement of light can be separated into a range of measurement principles. Each of these measurement principles is quantified according to different optical parameters. In the case of ...

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 ...
