A High Optical Density Measuring Spectrometer.
Abstract
An apparatus is disclosed for measuring the spectra of a high optical density sample having substantially known optical properties. In a preferred embodiment, the apparatus comprises: a laser for producing a light beam; a Raman cell responsive to the light beam for generating a first containing a plurality of preselected wavelength components; an optical system for directing the first light through the sample; a dispersion device for spatially separating the first light passed through the sample into its plurality of preselected wavelength components. Patent applications. (JES)
