Improved Raman-Emission Detector

Abstract

Improved apparatus excites and detects Raman emissions in sample gas mixture to measure concentration of species. Sensitivity increased by novel design features as increasing collection of emissions using paraboloidal reflector and collecting lens coaxial with beam instead of spherical reflector and condensing lens on axis perpendicular to illuminating beam.
