Direct reading intensified vidicon systems suitable for recording Raman spectra have recently become available. A chief point of interest in such systems is their speed. The full multiplex (Fellget's) advantage -- the ability to record a full spectrum with the speed of photoelectric detection -- means an increase in speed equal to the spectrum interval divided by the resolution. If 180 cm -1 are simultaneously recorded and the resolution is 3 cm -1, a 60 fold increase in speed is theoretically and practically attained. In this paper we will present details of an optical system well suited to detection of Raman spectra with a vidicon system, as well as details of the software controlled vidicon spectrum analyzer, the Television Optical Multi-Channel Analyzer or TOMCA. We will also show the applicability of the system to real time spectroscopic measurements of transient phenomena by presenting measurements of the classic iodine clock reaction.
