Abstract: An optoelectronic biosensor includes a housing with a transparent support surface. The optoelectronic biosensor also includes an emitter device in a first region of the housing adapted to generate and emit light toward the support surface. The optoelectronic biosensor further includes a detector device in a second region of the housing. The optoelectronic biosensor additionally includes a first optical fiber element between the detector device and the support surface. The first optical fiber element is configured to guide light incident on the support surface at an angle less than a predetermined angle to a normal to the detector device. The predetermined angle depends at least on a difference in refractive indices at an interface between the optical fiber element and a material surrounding the optical light guide element. A material of the first region surrounding the emitter device is the same as the material surrounding the first optical fiber element.

Abstract: A method for determining a substance concentration in a particle-containing liquid, in particular of glucose in blood, wherein a refractive index of the liquid is dependent on a concentration of the substance dissolved therein, includes emitting a measuring light beam of at least one wavelength onto a sample containing the liquid. The method also includes detecting a first light component scattered by scattering on the particles contained in the liquid at a first angle, which corresponds in particular to a forward scattering of the light component. The method further includes detecting a second light component scattered at a second angle by the particles contained in the liquid. The method additionally includes determining a concentration or a proportion of the substance in the liquid from the detected first and second light components, in particular by forming a ratio from the detected first and second light components.

Abstract: A radiation emitting device may have a plurality of emitters and a plurality of optical elements. The emitters may be arranged along a first emitter direction at a first average emitter spacing AE1 and along a second emitter direction extending obliquely or perpendicularly to the first emitter direction at a second average emitter spacing AE2. The optical elements may be arranged along a first optics direction at a first average optics spacing AO1 and along a second optics direction extending obliquely or perpendicularly to the first optics direction at a second average optics spacing AO2.
