This is the human body,
When pilots wear night vision goggles that form a visible light image by sensing infrared radiation emitted from equipment or other heat-dissipating objects, it indicates that infrared radiation is leaking from peripheral display devices when flying for night flight etc. This is because the entire device looks bright and hinders external observation.

However, too much alkali metal oxide deteriorates water resistance. Both N 2 O and K 2 O are at most 4% by weight (preferably about 1 to 3% by weight).

光透過率を達成している。As is well known, CuO absorbs a wide range of light from a red light having a wavelength of around 700 nm to an infrared region.
In the present invention this is used to color the glass blue and make it infrared absorbing. The amount is usually 3 to 8% by weight, preferably 3.5 to 7% by weight. However, since only Cu 2+ in the glass effectively acts in the glass, the ratio of CuO present in the form of Cu 2+ in CuO is made as high as possible to minimize the necessary CuO content. Is required to obtain bright blue light with high transmittance. Excessive CuO lowers the transmittance of blue light. In the present invention, a high degree of infrared shielding and a blue light transmittance of 65% or more are achieved with a small amount of CuO of 3 to 8% by weight (usually about 6% or less) by utilizing the action of auxiliary components described later. ing.

Has achieved a high degree of UV blocking. However, when these two components are added in excess, the transmittance is reduced beyond the near ultraviolet to the visible light region, and the transmitted light is changed to greenish blue. Thus, although the preferred addition rates of these components within a range that does not adversely affect the color of the transmitted visible light, it is necessary to determine in view of the ultraviolet shielding performance required, usually, CeO 2 is 0.1 3% by weight (preferably 0.5

る。The blue glass according to the present invention makes use of its high blue light transmittance, infrared ray blocking ability and ultraviolet ray blocking ability, and can be used for general filter glass, display devices, signal devices,
It can be used for building materials in the same way as conventional blue glass, but it can also be used in applications that need to block infrared and / or ultraviolet light without the need for an infrared (or ultraviolet) filter. It can be widely used for a simple blue filter, a display panel, a signal light, and the like, and also as a simple infrared filter or ultraviolet filter which does not necessarily need to be blue.
