Abstract
An optoelectronic component arrangement is indicated, which includes a radiation-sensitive detector element having a semiconductor base substrate with one or more doped partial regions and at least one partial layer which is arranged directly in front of the semiconductor base substrate. The detector element is arranged on a transparent carrier substrate, and a filling material is arranged between the carrier substrate and the surface of the detector element facing the carrier substrate. All materials arranged in front of the semiconductor base substrate and the doped partial regions have an essentially similar index of refraction.

An optoelectronic component arrangement comprising:
- a radiation-sensitive detector element having a semiconductor base substrate with at least one doped partial region and having at least one partial layer adjoining the semiconductor base substrate;
- a transparent carrier substrate, the detector element being arranged on the transparent carrier substrate;
- and
- a filling material between the carrier substrate and a surface of the detector element facing the carrier substrate;
- all materials in front of the at least one doped partial region in a direction of the carrier substrate having an essentially similar index of refraction.
A scanning unit of an optical position measuring device comprising:
- a radiation-sensitive detector element having a semiconductor base substrate with at least one doped partial region and having at least one partial layer adjoining the semiconductor base substrate;
- a transparent carrier substrate, the detector element being arranged on the transparent carrier substrate;
- and
- a filling material between the carrier substrate and a surface of the detector element facing the carrier substrate;
- all materials in front of the at least one doped partial region in a direction of the carrier substrate having an essentially similar index of refraction.
An optoelectronic component arrangement comprising:
- a semiconductor base substrate with at least one doped partial region at a first surface for detecting radiation;
- at least one partial layer adjoining the first surface;
- a transparent carrier substrate, the at least one partial layer being arranged on the transparent carrier substrate;
- and
- a filling material between the carrier substrate and the at least one partial layer;
- the at least one partial layer, the filling material and the carrier substrate having an essentially similar index of refraction so that at least part of the radiation passing to the base substrate experiences solely the similar index of refraction.
