Claims
- 1. An optical transmission channel comprising a one piece optically transmissive light guide member consisting of a transparent optical medium for transmitting light,
- said one piece member consisting of the optical medium having a longitudinal axis, and a generally cylindrical outer peripheral surface,
- said peripheral surface having at least one groove therein, said groove extending in a direction that is parallel to said axis, and
- said optical medium including at least one of PMMA (polymethylmethacrylate), PBMA (polyisobutylmethacrylate), PnBMA (polynormalbutylmethacrylate), polystyrene, polycarbonate and silicic rubber.
- 2. An optical transmission channel as set forth in claim 1, wherein said member has two longitudinally opposite ends and, said at least one groove extends from one of said two ends to the other of said two ends.
- 3. An optical transmission channel device comprising:
- a one piece optically transmissive light guide member consisting of an optical medium for transmitting light,
- said one piece member consisting of the optical medium having a first end and a second end opposite said first end, a longitudinal axis extending between said first end and said second end, and a generally cylindrical outer peripheral surface,
- said peripheral surface having at least one groove extending therein from said first end to said second end in a direction that is parallel to said axis; and
- at least one other member each of which extends in a respective one of said at least one groove, said at least one other member comprising another optically transmissive member, said at least one other member having a cross-sectional area that is substantially equal to the cross-sectional area of the respective groove in which it extends such that said at least one other member only substantially fills said groove in which it extends.
- 4. A device as set forth in claim 3, wherein said first member comprises an illuminating light transmission channel and said other member comprises an image fiber.
- 5. A device as set forth in claim 4, wherein said at least one groove includes two grooves, and further comprising a longitudinally extending tube for carrying air from said first end to said second end extending in one of said two grooves, said image fiber being disposed in the other of said two grooves.
