Abstract: In an embodiment an optoelectronic apparatus includes a light detector having a bottom side, an upper side and at least one sidewall that extends between the upper side and the bottom side, a carrier having an upper surface on which the light detector is arranged such that the bottom side faces the carrier, at least one outer wall which is arranged on the surface of the carrier, the outer wall and the carrier forming a cavity with an opening in which the light detector resides, a filter covering the upper side of the light detector, the filter having a first threshold wavelength separating a first wavelength region from an adjacent second wavelength region, wherein the filter has a lower transmittance for light at wavelengths in the first wavelength region than for light at wavelengths in the second wavelength region and a first material layer covering the filter.

Abstract: In an embodiment a sensor device includes a housing having at least a first cavity and a second cavity, at least one light emitter arranged in the first cavity and at least one light detector arranged in the second cavity, wherein each of the cavities has an opening at an underside of the housing so that light from the respective cavity is passable to the outside and/or from the outside into the respective cavity, wherein each of the cavities includes a bottom opposite the underside of the housing and a peripheral side wall extending between the bottom and the underside of the housing, wherein at least one of the cavities is filled with an absorbing material from the bottom to a specified height, and with a transparent material from the specified height to a height of the underside of the housing, and wherein the light detector is arranged on the bottom of the second cavity.
