Abstract

The sensor has at least one light waveguide with multiple windings in the detection region. Stray light is coupled into the waveguide through the sleeving and passed to a sensor. The waveguide is held or fixed in a base body. At least one optical element (42',52) associated with the base body amplifies the stray light yield. The optical element is a transparent body (42') with fluorescence centers (52) for absorbable radiation.
