Abstract
A spectrograph for analyzing the chemical composition of a sample is disclosed. Scattered light from a sample cell is collected by one or more optical fibers and is introduced into a collimating lens as a linear optical signal. The collimating lens directs the optical signal to a reflective diffraction grating which reflects the signal into a focusing lens. The focusing lens focuses the optical signal onto a charge coupled device array which converts the optical signal into a electronic signal. Aberration correction is provided by the collimating and focussing lenses. The electronic signal is analyzed and converted by computer into a representation of the chemical analysis of the sample stream.
