Abstract

The invention relates to an optical system for measuring the absorption of light in a medium, comprising at least one light source for sending light and at least one optical detector, which receives the light and converts it into an electrical signal. The system is characterized in that the system comprises at least one light guide, wherein, in the region of the light source, light is coupled as reference light into the light guide, wherein the light guide is guided, at least in sections, past the medium, and wherein the light guide guides the reference light onto the detector.
