Detection arrangement and method for producing detection arrangements

A detection arrangement comprising:

• an emitter configured to generate radiation having a peak wavelength in an infrared spectral range;
• a detector configured to receive the radiation;
• a mounting surface comprising at least a first contact surface and a second contact surface for external electrical connection of the detection arrangement;
• a form body adjoining the emitter and the detector at least in places;
• and
• deflection optics configured to deflect the radiation during operation of the detection arrangement so that an optical path is formed between the emitter and the detector by the deflection optics, the deflection optics covering only a portion of the optical path,
• wherein the deflection optics comprise a scattering body having a first surface into which the radiation enters the scattering body and a second surface from which the radiation exits the scattering body during the operation, wherein the first surface faces the emitter and the second surface is non-parallel to the mounting surface,
• wherein the optical path extends parallel to the mounting surface in places,
• wherein the scattering body comprises a crystal structure, and
• wherein defects in the crystal structure are configured to cause scattering.
