Optoelectronic sensor comprising an optical filter element arranged without a gap between first and second part lenses of at least one reception lens

An optoelectronic sensor, comprising:

• a transmission element,
• at least one transmission lens, and
• an optical filter element,
• wherein the filter element is arranged without a gap between a first part lens and a second part lens, with the part lenses forming one of the transmission lenses or the transmission lens, and with the optical filter element having at least one convex or concave shape and transmitted light beams passing through the filter element at the same angle at every entry point.

An optoelectronic sensor, comprising

• a reception element,
• a reception lens, and
• an optical filter element that is arranged between the reception element and the reception lens,
• wherein the optical filter element has at least one curved free-form surface so that the received light beams pass through the filter element at the surface of the optical filter element at the same angle at every entry point.
