    摘要: Provided is a method that can manufacture a large-sized glass material by containerless levitation. A glass raw material block (13) is placed on a forming surface (11a) having a plurality of gas jet holes (12a) opened thereto, gas is jetted through the plurality of gas jet holes (12a) to hold the glass raw material block (13) levitated above the forming surface (11a), and the glass raw material block (13) held levitated above the forming surface (11a) is melted by heat and then cooled to obtain a glass material.

    摘要: The present invention achieves an infrared imaging lens which is excellent in performance capability such as aberration despite its wide angle of view and which is adaptable to a far infrared region.
    An infrared imaging lens (1) includes: a first lens (L1) having negative refractive power; a second lens (L2) which is a meniscus that is convex to an image surface side; and an image surface side lens group (G) having positive refractive power, the first lens, the second lens, and the image surface side lens group being disposed in this order from an object side to the image surface side, the first lens and the second lens each being made of glass having a refractive index of not less than 2.8 measured at a wavelength of 10 μm, and the infrared imaging lens having a half angle of view of not less than 60°.

    摘要: Provided is an optical cap component that can give good sensitivity to an infrared light absorption-based optical gas sensor. An optical cap component includes: a window member formed of a lens-shaped infrared transmitting glass; and a cap member including a cylindrical sidewall portion having openings on both a distal end side and a base end side, wherein the window member is fixed to cover the opening on the distal end side of the cap member.

    摘要: Provided is a small-diameter chalcogenide glass material having excellent weather resistance and mechanical strength and being suitable as an optical element for an infrared sensor. The chalcogenide glass material has an unpolished side surface, a pillar shape with a diameter of 15 mm or less, and a composition of, in terms of % by mole, 40 to 90% S+Se+Te and an inside of the glass material is free of stria with a length of 500 μm or more.

    摘要: Provided is a novel infrared-transmitting glass that can be vitrified without containing any environmentally harmful compound and has high light transmissivity from visible range to a mid-infrared range of wavelengths of about 4 to about 8 μm. An infrared-transmitting glass containing, in % by mole, 50% or more TeO2, 0 to 45% (exclusive of 0%) ZnO, and 0 to 50% (exclusive of 0% and 50%) RO (where R is at least one selected from the group consisting of Ca, Sr, and Ba).
