Although it contains coloring components such as e2O2, NiO, Pr6011, etc., the absorption edge on the short wavelength side is not sharp enough, and the absorption near 500 nm is not sufficient, so the color contrast is not necessarily satisfactory. There is. Additionally, since this glass was developed for color CRT display devices, its light absorption characteristics are matched to the coloring peak of the phosphor, making it ideal for eliminating the effects of reflected light on color CR7 display tubes. Of course,
However, it is not suitable for increasing the color contrast of the outside world on the instep.

S! Oz is a basic glass component, and if its ω exceeds 70%, the viscosity of the glass becomes too high, making it difficult to melt, and the solubility of Ndz03 decreases, making it difficult to vitrify. If it is less than 3%, B203 cannot be vitrified unless B203 coexists in a relatively wide range, and the chemical durability required for use cannot be obtained. Bz O3 is S! -C1 is a glass network forming component that can be substituted for 02.
40% because it has the effect of increasing the solubility of jzoJ.
Although it is possible to blend up to 40% C, the chemical durability will deteriorate if more than 40% is used. In addition, B20:l is used to adjust the amount of green light.
It is an effective component when using O-'6 color.

If the blending ratio exceeds 23%, it becomes difficult to melt the glass. R20 is a component that improves the solubility of glass, but if it exceeds 23%, it deteriorates the chemical durability of glass.

It is important that the blending amount of the RO component accounts for 35 to 40% of the basic glass composition; if it falls below this range, not only will it be impossible to sharply cut the absorption edge on the short wavelength side, but also it will not be possible to sharply cut the absorption edge on the short wavelength side. It also cannot absorb enough of the surrounding area. Among the RO acid components, especially PbO1sa
o and sro are effective additive components when a high refractive index is required. The upper limit for the amount of RO acid component blended is 40%, and if it is used above this, the chemical durability of the glass will deteriorate significantly, making it unusable.

It strengthens the coloring of 2 and contributes to absorption in the visible short wavelength region and adjustment of the amount of blue light, but if it is added in excess of 10%, the glass tends to devitrify. ZrO2 has the effect of increasing chemical durability, but if it exceeds 10%, it becomes difficult to melt. Shia20
:+ is not a coloring component, but it has properties very similar to N (jz03), so in order to increase the chemical durability and hardness of the glass, up to 35% C can be added by replacing it with NdzOx. However, if it exceeds 35%, the glass tends to devitrify.NbzOs, -ra20s can be added to increase the chemical durability and hardness of the glass, but it is a very expensive component. , it is meaningless to add more than 5%.

In the present invention, Nd2O3 is an essential component that is effective in separating the three color lights of blue, green, and red in order to increase the color contrast, and if the amount of Nd2O3 is less than 5%, the effect of separating the three color lights is poor. . However, even if the content exceeds 40%, the effect will not increase, but rather the glass will become more likely to devitrify.

When Nd2O3 content ω is relatively small, the color appears magenta under natural light and blue under fluorescent lighting. However, a glass containing 5% or more of Nd2O3, such as the glass of the present invention, has very strong absorption in the green light range, and therefore has a strong magenta color even under fluorescent lighting. In order to faithfully display a color image without changing its hue, the hue of the filter must be achromatic. However, as mentioned above, glass containing 5% or more of Nd2O3 exhibits a magenta color, so simply combining achromatic filters or introducing a single coloring component will not produce an achromatic filter glass. In order to make the hue of the glass achromatic, it is necessary to reduce the transmittance of blue light and red light in response to the amount of green light reduced by Nd3+ ions, but in this case, the transmittance of blue light and red light can be reduced. By absorbing light of other wavelengths without reducing the transmittance near the red peak wavelength as much as possible, it is possible to obtain a high-brightness, high-contrast achromatic filter glass. .

Ge0z has light absorption in the visible short wavelength range, and is used to absorb light in this range and adjust blue light transmittance, but a blend of 6% or less per 100-type basic glass can is sufficient for the purpose. It can be achieved. A suitable amount is 0.5-6.0% by weight.

CuO, contrary to Ce0z, has light absorption in the pJ current long wavelength light region, and is very effective in absorbing light in this region and adjusting the red light transmittance. However, if the blending amount exceeds 10% by weight per 100 parts by weight of the basic glass, the coloration becomes too much il'A< and the red light transmittance becomes too low. CuO
The suitable LtO is in the range of 01 to 0.5i%. F
Since ezO3 absorbs light at both long and short wavelengths of visible light, it is used to adjust the transmittance of blue and red light.
If the blending amount exceeds 3.0% by weight per 100 parts by weight of the base glass, the color density will become too high. MnO
2 and CoO absorb blue light and green light, and light in the intermediate wavelength range between green light and red light, respectively, and are effective components for further reducing green light transmittance.
Less than 0.01% by weight of MnO and 0.0% of CoO per tit part
If the weight ratio is less than 0.01, sufficient effects cannot be obtained. However, 3.5% by weight of MnO2r and 0.1% by weight of CoO
If it exceeds 5%, the coloring tends to become too dark.

NiO exhibits strong absorption in the blue light region and is effective in adjusting the blue light transmittance, but if the amount exceeds 0.151ffl't% per 100 parts by weight of the base glass, the blue light transmittance will be lowered. This is not preferable because it lowers the value more than necessary.

(Left below) [Effects of the Invention] As seen in the spectral transmittance shown in the drawing, the glass of the present invention separates the three color lights of blue, green, and red well, so the outside world can be observed through a filter obtained from this glass. Alternatively, if the image is shaded, an image with a vivid color contrast can be obtained. Furthermore, since the hue is gray or close to gray, the colors of the image can be faithfully reproduced. Furthermore, even when a high refractive index is required for a filter, the glass of the present invention can be used with pb○,
Since it is possible to incorporate a large amount of Bad and SrO,
Another advantage is that such filters can be easily obtained. Furthermore, it goes without saying that the glass of the present invention can also be effectively used as a contrast filter for color CRT display devices.
