FT500: A High Resolution VUV FTS: The Why and the How

Abstract

The advantages of the FTS over the classical grating spectrometer are clear - the fundamental gain is increased luminosity, with a consequent increase in the rate at which the spectrometer records basic information. Associated, but less fundamental gains include linearity in both intensity and frequency. An indirect but very real gain is the integration of computer and spectrometer, aiding the rapid and direct analysis of large quantities of data.
