摘要： An optical sensor arrangement comprises an optoelectronic device covered by a cover arrangement and being configured to emit or detect at least electromagnetic radiation with a first wavelength through an aperture of the cover arrangement. The optical sensor arrangement further comprises a mirror arrangement arranged between the optoelectronic device and the aperture and comprising a wavelength selective mirror with a passband and a stopband. The passband includes a first wavelength range including the first wavelength, the stopband includes a second wavelength range corresponding to visible light or vice versa.

摘要： An optical sensor arrangement comprises an emitting device (E) and a detection device (D) configured to emit and detect, respectively, electromagnetic radiation and a cover (C) arranged to cover the emitting and the detection device (E, D). The sensor arrangement comprises a first cover layer (C1) partially covering an inner surface of the cover (C) and having a first and a second opening located above the emitting and the detection device (E, D), respectively. The sensor arrangement comprises a second and a third cover layer (C2, C3) covering the inner surface at areas of the first and the second opening. A reflection and/or an absorption characteristics of at least one of the second and third cover layer (C2, C3) is adapted to a reflection and/or an absorption characteristics of the first cover layer (C1) for incident light within the specified spectrum.

摘要： An optical sensor arrangement comprises an optical barrier which is placed between a light-emitting device and a photodetector. Herein the light-emitting device and the photodetector are arranged on a first plane and are covered by a cover. The photodetector exhibits an active zone. The optical barrier exhibits an extent along a first principal axis, which is pointing parallel to the line connecting the centers of the light-emitting device and the photodetector. Herein the extent is greater than a dimension of the active zone. The optical barrier is designed to block light emitted by the light-emitting device that otherwise would be reflected by the cover by means of specular reflection and would reach the photodetector. The optical barrier is designed to pass light emitted by the light-emitting device and scattered on or above an outer surface of the cover.
