Abstract
Calibrating reflector device to calibrate an optical measuring system having an optical fiber optics probe, for example, for measuring the oxygen saturation of blood. The calibrating reflector device comprises a housing that is open on one end, a reflecting device in the form of an opaque layer in which reflecting particles are embedded, as well as a positioning plug with a central bore, in which the fiber optics probe can be received with a certain frictional resistance. A transparent layer is disposed between the front end of fiber optics probe and the reflecting layer, on whose surface the front end of fiber optics probe can be arranged by the positioning plug.
