  • the vicinity of the connection area is preferably formed by one side of the carrier, preferably a rear side of the carrier.
  • optical element is formed by an approximately cylindrical monolithic body which is approximately cylindrical and comprises both the radiation-shaping region and the connection region, which in turn is held in a carrier.
  • the cylindrical body itself forms the connection surface, which in turn is then offset from the surroundings, that is to say from the rear of the carrier.
  • connection surface can either be achieved in that the monolithic body protrudes beyond the rear like a protrusion or is set back relative to the rear and thus a recess is formed starting from the rear, which extends to the connection surface.

  • the radiation field-forming region has a refractive index gradient for the radiation field formation.
  • the radiation field-forming region is preferably formed by a cylindrical monolithic body with GRIN optics.
