    摘要: An object of the present invention is to provide a synthetic quartz glass optical material having a high optical transmittance for a radiation 157 nm in wavelength emitted from F2 excimer laser and a high resistance against irradiation of a F2 excimer laser radiation, yet having a uniformity suitable for such a fine patterning using a F2 excimer laser, and to provide an optical member using the same. The problems above are solved by a synthetic quartz glass optical material for F2 excimer lasers having an OH group concentration of 0.5 ppm or lower, a fluorine concentration of 0.1 to 2 mol %, a hydrogen molecule concentration of 5×1016 molecules/cm3 or lower, a difference between the maximum and minimum fluorine concentrations within 20 mol ppm, and a difference between the maximum and minimum refraction indices of 2×10−5 or lower.

    摘要: An optical connector has a ferrule for accommodating an optical fiber. The ferrule includes a glass capillary and a coating. The glass capillary is formed at the distal end portion of the ferrule and is inserted in a ceramic sleeve that performs optical connection. The glass cylinder has a first through hole at the central axis portion thereof to accommodate a bare optical fiber. The coating is made of a material having a higher hardness than that of the sleeve, and coats an entire outer circumferential surface of the glass capillary. A method of manufacturing an optical connector is also disclosed.
