Light coupling from optical fiber to glass?

[QUOTE="Mary09, post: 6830726, member: 731565"] Many thanks for your answers! I have attached a sketch. The glass capillary is used to melt in a small metal wire which is then used as an electrode. The idea is to use the glass fiber both for insulation of the metal wire and for local illumination as we want to study photocatalyst reactions on a surface. My question is how to position the optical fiber for the coupling? -Directly on one side of the glass sheath? Therefore the diameters of the fiber (0,4mm) and sheath (0,25mm) would not match now. Maybe with a smaller fiber then? 0,4 is the smallest we have right now -Illuminate both glass sheath and air with the bigger fiber? (Also directly place the fiber in physical contact with the capillary) -Another idea would be to melt the glass end of the capillary and use it as a lens to collimate the light? [/QUOTE]
