Light coupling from optical fiber to glass?

[QUOTE="tech99, post: 6830917, member: 477979"] Today I tried shining a torch [flashlight] into a glass rod. It works really well as a light guide. Then I tried shining the torch into a glass tube. In this case the light is guided mostly through the glass rather than through the hollow centre. I tend to think that any light source placed against your capillary tube will shine effectively through the glass and emerge at the end. In order to illuminate the glass rather than the hollow centre, I suggest trying the 1 mm fibre butted against the end of the capillary. [/QUOTE]
