Abstract
The invention described here is an improved fiber optic probe. The tip of the probe is made from a transparent fill material that is connected to the end of a conventional optical fiber. The optical fiber is tapered, the fill material is connected thereto, and typically extends outwardly from the fiber as though it is a continuous part of the fiber. The outer diameter of the fill material is preferably essentially the same as the optical fiber. The fill material may contain light-scattering elements that disperse light as it exits the fiber.
Claims19
A fiber optic probe, comprising:
- an optical fiber having an outer diameter and a tapered end, the tapered end providing a surface area;
- a terminal material that is made of a material different from the material of the optical fiber wherein:
- i. the terminal material is connected to and located in front of the tapered end of the optical fiber, the terminal material being bonded to the surface area of the tapered end;
- and
- ii. the terminal material has an outer diameter that is substantially the same as the outer diameter of the optical fiber;
- and
- a cladding surrounding the optical fiber and covering the probe at a region where the optical fiber and the terminal material are connected together;
- wherein the terminal material includes a plurality of light-scattering elements or has inherent light scattering elements.
A fiber optic probe, comprising:
- an optical fiber having an outer diameter and a tapered end, the optical fiber being surrounded by a cladding;
- a terminal material that is made of a material different from the material of the optical fiber wherein:
- i. the terminal material is connected to and located in front of the tapered end of the optical fiber;
- ii. the terminal material has an outer diameter coaxial with the tapered end of the optical fiber;
- and
- iii. the outer diameter of the terminal material surrounds the tapered end and the outer diameter of the terminal material is less than an outer diameter of the cladding.
