Abstract: An illumination device for fluorescence image guided surgery and a surgical instrument. The illumination device includes a glass rod, a mixing rod and a plurality of optical fibers surrounding a circumferential surface of the glass rod. A first mixing rod end face of the mixing rod abuts a second rod end face of the glass rod and end faces of the optical fibers, so that white light and excitation light are guided and homogenized in the mixing rod.

Abstract: A honeycomb body for exhaust gas aftertreatment includes a plurality of interconnected metal foils stacked on one another. The honeycomb body has a central first flow channel running in the axial direction of the honeycomb body, as an inflow section, and has a plurality of second flow channels between in each case two mutually adjacent metal foils. The first flow channel is in fluid communication with the second flow channels. The second flow channels formed between two mutually adjacent metal foils run in a straight line and parallel to one another along a radial direction of the honeycomb body.
