Abstract

The equation of Jacquinot for the output power P of spectrometers is generalized to include spectrographs. By means of the concepts of responsivity and detectivity, one may then compare spectrographs equipped with photographic and photomissive sensors.

If area A is an adjustable parameter, e.g., by choice of dispersion, slit height, emulsion resolution, or exit slit width, then/it is neither P nor P/A, but rather P/A1/2 that is to be maximized for best analytical precision or limit of detection.
