摘要

The spectroscopic sensor (1) has an infrared radiation source (2) for emitting infrared radiation (3), an absorption passage (4) for receiving a gas or a liquid, and an optical filter (5) for wavelength-selective transmission of the infrared radiation arriving through the absorption passage. The infrared radiation source and a detector (6) are fastened on a circuit board. The absorption passage is formed as an inner chamber of a reflecting device. A direct radiation transfer from the infrared radiation source to the detector without reflection at the reflecting device.
