Sensor and use of a sensor in a 3-D position detection system

A sensor comprising:

• at least one sensor chip configured to detect radiation;
• at least one carrier on which the sensor chip is mounted;
• and
• a cast body that is transmissive for the radiation and that completely covers the sensor chip,
• wherein a centroid shift of the sensor chip amounts to at most 0.04 mrad at an angle of incidence of up to at least 60°,
• wherein the cast body comprises a light inlet side that faces away from the sensor chip, and the light inlet side comprises side walls bounding it on all sides,
• wherein the side walls are smooth, planar and transmissive for the radiation,
• wherein a free field-of-view on the light inlet side has an aperture angle of at least 140°,
• wherein the sensor chip is contacted electrically with at least one bond wire, and
• wherein the cast body protrudes in a direction away from the sensor chip beyond the bond wire by at most 120 μm so that a thickness of the cast body at the side that faces away from the sensor chip lies at a maximum of 0.2 mm and so that the thickness is smaller than a thickness of the sensor chip.
