Estimating the term…
A light guide device for conducting a light beam between a light source and a measuring unit for measuring a gas or substance concentration includes a light conductor and a holding apparatus. The conductor includes at least one coupling section, which faces, or can be arranged to be turned toward, the light source, for coupling the light beam, and a decoupling section, which faces, or can be arranged to be turned toward, the measuring unit, for decoupling the light beam. The conductor is configured to conduct the light beam between the coupling section and the decoupling section via total reflection on a boundary surface to a fluid or material that surrounds the conductor and has a smaller refractive index than the conductor. The holding apparatus is configured to hold the conductor in the fluid such that at least one primary portion of a surface of the conductor contacts the fluid.
A light guide apparatus for guiding a first light beam between a light source and a measuring unit, which contains a gas or substance and is configured for measuring a gas concentration of the gas or substance concentration of the substance, the light guide apparatus comprising:
A measurement system, comprising:
A method for producing a light guide apparatus for guiding a light beam between a light source and a measuring unit, which contains a gas or substance and is configured for measuring a gas concentration of the gas or substance concentration of the substance, the method comprising:
