In a fibre optic device 1 for observing an object 4 by an eye 8, in order to illuminate the object 4 without increasing the size of the device 1, the light from a source 5 is introduced at a position 7 where the fibres change direction. As shown a prism 9 having the same refractive index as the cladding of the fibres is attached at the bend 7. In a modification the fibre optic device has a tapered portion to which a prism is attached for introducing the light. |
