    摘要: Provided is an ATR prism, including a material having an internal transmittance of 90% or higher at a wavelength falling within a wavelength range of from 8 μm to 10 μm, when the material has a thickness of 2 mm. The ATR prism includes: a first surface including a first totally reflecting surface; a second surface including a second totally reflecting surface; and a recessed portion formed in one of the first surface or the second surface.

    摘要: Provided is a method of manufacturing a glass film, including a cleaving step (S5) of cleaving a band-like glass film (G1) conveyed in a predetermined conveying direction (X) through irradiation of the glass film (G1) with a laser beam (L). The cleaving step (S5) includes: a step of, while supporting a lower surface of the glass film (G1) by a surface plate (22) including an opening (25a), suctioning the glass film (G1) through the opening (25a); and a step of irradiating the glass film (G1) suctioned through the opening (25a) with the laser beam (L).

    摘要: A method of manufacturing a glass sheet includes a start point forming step of forming a scribe line on a preset cutting portion of a glass sheet, a setting step of causing, through use of a support member having a groove-shaped recess, the support member to support the glass sheet having the scribe line formed thereon from one surface side so that the preset cutting portion is arranged on the recess, and a cutting step of generating a negative pressure in the recess to bend the preset cutting portion on the recess so that the one surface side protrudes, to thereby cut the glass sheet along the preset cutting portion with the scribe line as the start point. At the time of performing the cutting step, the entire recess is covered with a cover member from another surface side of the glass sheet through intermediation of the glass sheet.
