quantum efficiency

(QE)
(measure of instrument's ability to sense EMR)

The term quantum efficiency (QE) is used for a measure of an instrument's ability to sense EMR, consisting of the fraction or percent of photons sensed/counted. For a particular instrument, it is a function of wavelength (a type of sensitivity function). The measure is commonly cited for CCDs, and is applicable to other EMR-sensing instruments such as photomultiplier tubes, and processes such as photography. It may be stated as that applying to some particular wavelength-range.


The term quantum efficiency also has other uses, some of which are analogous, such as for power-generating solar cells.
