発明の名称 (英語) Optical fiber for transmitting ultraviolet ray, optical fiber probe, and method of manufacturing the optical fiber probe 実績あり
発明の概要(英語) It is an object of the present invention to provide an optical fiber for transmitting ultraviolet ray which has an improve transmittance and is prevented from deterioration by ultraviolet ray with which it is irradiated. It is another object of the present invention to provide an optical fiber probe which can propagate vacuum ultraviolet ray and deep ultraviolet ray at a high transmittance, is deteriorated only to a limited extent when irradiated with ultraviolet ray and can be etched to have a desired shape of the sharpened section at the fiber end.The present invention provides the optical fiber for transmitting ultraviolet ray which has a core 5 of silica glass containing a given content of fluorine and a clad 6a of silica glass containing a given content of fluorine or boron, a clad 6b of a resin which transmits ultraviolet ray or a clad 6c having air holes H. The clad may be coated with a protective layer and further with a covered layer for protection. In particular, the core, clad and protective layer have a high transmittance for ultraviolet ray and resistance to ultraviolet ray with which they are irradiated, when treated with hydrogen.An optical fiber probe 1 has an optical fiber 2 provided with a sharpened section 3 at the end, which is sharpened with an etchant solution, the sharpened section 3 being coated with a light-shielding metallic film 4.
