Abstract
An optical waveguide with a tubular or hose-like housing is provided, which is used in a high-temperature environment, such as, for example, in a burner. The housing has an input opening, an output opening and a center line extending from the input opening to the output opening. In the interior of the housing, transparent spheres are lined up along with center line. The light is guided on account of the refraction of a light beam upon entering and exiting from the transparent spheres.
