How the Flame Spectrometer

Works

Overview

This section provides an overview of the Flame spectrometer and how it works from light

entering the slit through to the transmission of the spectrum over USB. It also provides an

overview of all the different possible configurations that are possible, designed to help you

optimize your spectrometer for specific applications.
You’ll find more useful information, including a

glossary of spectroscopy and spectrometer
