Abstract: The main object or purpose of the present invention is to provide a glass material that is suitable for mold forming, can reduce the size, and allows rays having a wavelength region between visible light to far-infrared light to pass through. To overcome this object, the present invention provides a glass material allowing rays having a wavelength in the region from visible light to far-infrared light to pass through, the glass material comprising, in terms of molar concentration: 50 to 70% of S, 15 to 30% of Ge, 5 to 20% of Ga, 0.5 to 15% of Ba, and 3 to 15% of at least one member selected from the group consisting of Cl, Br, and I, with the proviso that when the Cl is present alone, the molar concentration is 6 to 15%.

Abstract: An optical sensor device includes a resin sealing portion for sealing an optical sensor element fixed to an element-mounting portion. The resin sealing portion is constituted of a resin having mixed and dispersed therein a glass filler obtained by pulverizing a phosphate-based glass which has spectral luminous efficacy properties by composition adjustment and high heat resistance and weatherability. The optical sensor device is highly reliable and capable of accommodating size and thickness reductions in packages and has stable and hardly changeable spectral luminous efficacy properties.

Abstract: An optical sensor device comprises an element-mounting portion, an optical sensor element provided on the element-mounting portion, a lead having a first contact region connected to the optical sensor element and a second contact region for an external connection, and a resin-encapsulating portion which covers at least a light-receiving plane of the optical sensor element. The resin-encapsulating portion comprises a resin and a glass filler including borosilicate glass dispersed in the resin. The transmissivity of the resin-encapsulating portion in one example is equal to or more than 40% in a wavelength range between 300 nm to 400 nm, and in another example is equal to or more than 60% in a wavelength range between 300 nm and 350 nm.

Abstract: The following configuration is adopted in order to provide a highly reliable optival sensor device which enhances the reliability of devices without making the devices unsuitable for size and thickness reductions. The light sensor comprises an element-mounting portion (3) having a cavity and a lid member closely attached thereinto, the lid member being composed of: a window (2) constituted of a phosphate-based glass to which properties approximate to a spectral luminous efficacy properties have been imparted by compositional control; and a frame (1) constituted of a phosphate-based glass having light-shielding properties.
