Abstract: An illumination system for a medical technology therapy and/or diagnosis system is provided. The system includes a light source, an optical waveguide, and an optical element in the form of a diffuser element. The optical waveguide has a first end that is connectable or assignable to the light source and the diffuser element is arranged at a second end of the optical waveguide so that light from the optical waveguide is injected into the optical element. The optical element has a lateral surface covered by a reflector layer at least in a section thereof. The reflector layer includes a mirror layer. The optical element has a light-reflecting area covered by the reflector layer and a light-transmissive area that is free of the reflector layer. Thus, light injected into the optical element is reflected on the light-reflecting area and emitted from the light-transmissive area.

Abstract: A method for manufacturing a MEMS sensor. The method includes: providing a substrate, applying a support layer onto a back side of the substrate, forming at least one cavity in the substrate in such a way that an access to the back side from the front side is formed, introducing a MEMS structure into the at least one cavity, and fixing the MEMS structure on the support layer.

Abstract: A method for producing a plurality of sensor devices. The method includes: furnishing a substrate having contact points in a plurality of predetermined regions for sensor chips; disposing the sensor chips in the predetermined regions on the substrate, and electrically contacting the sensor chips to the contact points; attaching a frame structure with an adhesive material on the substrate and between the sensor chips, the frame structure proceeding laterally around the sensor chips, the frame structure extending, after attachment, vertically beyond the sensor chips and forming a respective cavity for at least one of the sensor chips, and a membrane spanning at least one of the cavities for the sensor chips so as to cover it; and singulating the substrate, or the frame structure and the substrate, around the respective cavities into several sensor devices.
