US 2017/0284933 A1 · Integrated Ultraviolet Analyzer

Abstract

An integrated ultraviolet analyzer is described. The integrated ultraviolet analyzer can include one or more ultraviolet analyzer cells, each of which includes one or more ultraviolet photodetectors and one or more solid state light sources, which are monolithically integrated. The solid state light source can be operated to emit ultraviolet light, at least some of which passes through an analyzer active gap and irradiates a light sensing surface of the ultraviolet photodetector. A medium to be evaluated can be present in the analyzer active gap and affect the ultraviolet light as it passes there through, thereby altering an effect of the ultraviolet light on a ultraviolet photodetector.
