FWHM

The width of a peak or the bandpass of an emission or absorption spectrum in a laboratory photometer or spectrophotometer. When combined with other characteristics of the device, this can be used to predict suitability of the photometer or spectrophotometer for specific applications and measurements.

The intrinsically narrow instrumental contribution of BM16 to the FWHM allowed the particles' growth to be followed to a grain size of about 500 nm, whereas for a laboratory instrument the limit is 100 nm.
