Patent number: 11885928Abstract: A functionalized waveguide for a detector system includes an incoupling region of a main body that deflects only part of the radiation coming from an object to be detected and impinges on the front face such that the deflected part propagates as coupled-in radiation in the main body by reflections up to the decoupling region and impinges on the decoupling region. A decoupling region deflects at least part of the coupled-in radiation impinging thereon such that the deflected part exits the main body via the front or rear face to impinge on the detector system.

Patent number: 11460407Abstract: For the purpose of gas quality monitoring, a spectroscopic examination of a gas sample from a space (10) to be monitored is carried out, e.g. by Raman spectroscopy. The spectroscopic examination yields a measurement spectrum extending over a wavelength range. A deviation of the measurement spectrum from at least one comparison sample (160) is then detected. Depending on the detected deviation, a gas quality warning (QW) is produced.Type: GrantFiled: August 2, 2018Date of Patent: October 4, 2022Assignees: Carl Zeiss Jena GmbH, Carl Zeiss Spectroscopy GmbHInventors: Michael Rode, Alexandre Gatto, Arnaud Deparnay, Michael Helgert
