    摘要: A fluorescence observing apparatus has an illumination system for irradiating a specimen with exciting light and an observation system for observing fluorescent light emanating from the specimen. Low-fluorescence glass is used for lenses of the first and seventh lens units of an objective lens used in both the illumination system and the observation system. The low-fluorescence glass has a platinum content of less than 1 ppm. Whereby, high-precision and high-quality fluorescence observations and fluorescence measurements become possible.

    摘要: An infrared absorption filter consisting of 70 to 98 mol % of SiO2, 1 to 12 mol % of CuO and 1 to 18 mol % of a network modifier oxide than CuO or CdO is provided. A process of fabricating an infrared absorption filter is also provided. The process comprises introducing a divalent copper compound and a compound of a metal species acting as a network modifier oxide in the form of metal ions into a wet gel. The wet gel can be dipped in a dipping solution to precipitate the divalent copper compound and the compound of a metal species acting as the network modifier oxide in the wet gel. The wet gel can be dried and heated, thereby obtaining an infrared absorption glass. The infrared absorption glass can be cut and polished, thereby fabricating a filter.

    摘要: A gradient-index optical element comprises SiO2, BaO, and TiO2 as essential components, and has a refractive index profile in its diametrical direction. The molar ratio of barium to silicon at the center of the element in its diametrical direction is limited to Ba/Si≧0.4. This gradient-index optical element has a small refractive index difference with reduced chromatic aberrations and, hence, is suitable for use with optical equipment.
