Abstract: An anti-reflective film-attached transparent substrate includes: a transparent substrate having two main surfaces; and a diffusion layer and an anti-reflective film in this order from a transparent substrate side on one main surface of the transparent substrate. When reflection on the other main surface of the transparent substrate is eliminated and a light source is incident on the one main surface at an incident angle of 45°, a* and b* of diffusely reflected lights at angles of −15°, 15°, and 25° with respect to a specularly reflected light under a D65 light source satisfy formulas (1) −5≤a*≤−1 and (2) 0≤b*≤9.

Abstract: There is provided a vehicle glass that appropriately transmits far-infrared rays and has shock resistance. A vehicle glass (1) includes a glass member (10) in which an opening (19) penetrating the glass member (10) from a surface on a vehicle exterior side to a surface on a vehicle interior side is formed and a transmissive member (20) that is disposed in the opening (19), and has an average internal transmittance of 50% or more for light having a wavelength of 8 μm to 13 μm. A ratio Sa/Sb of fracture velocity Sa [km/h] measured on a surface on the vehicle of the transmissive member (20) by a chart stone chipping test and fracture velocity Sb [km/h] measured on the surface on the vehicle exterior side of the glass member (10) is 0.7 or more.

Abstract: A circular glass substrate including first and second main surfaces opposite each other, an edge portion between the first and second main surfaces, and a notch at a part of the edge portion. The glass substrate has a specific gravity of 3.00 or more; a radius r of 75 mm or more; a refractive index nd of 1.800 or more; and a ratio (Tf/Tg) of a fictive temperature Tf (° C.) to a glass transition temperature Tg (° C.) of 1.00 or more. In a relationship of an internal transmittance to a wavelength, when converted for a thickness of 10 mm, a shortest wavelength λ70 at which the internal transmittance becomes 70% is 440 nm or less; and a ratio (g/r) of deviation g (mm), of a center of mass (G) relative to a center (P), to the radius r, in a top view, is in a range of 0.05% to 1.2%.
