Description of the Invention: [Technical Field of the Invention] The present invention relates to the field of glass technology, and more specifically, to an absorption type near-infrared ray-glass, which is a fluorophosphate-based composition Based on the addition of light energy control additives. This glass is mainly used in imaging and related fields. [Prior Art] The image sensing element used in the image module of the digital image product has a sensing range of light waves of 400 nm to 1100 nrr, including visible light to near infrared light (ii 〇〇 nm). It is necessary to use near-infrared filter glass for the visible light sensitivity and color correction function of the eye. The conventional image sensing device uses a reflective near-infrared irradiance glass to filter out near-infrared rays having a wavelength of 700 to 11 〇〇 nm to avoid color shift, noise, and heat generation of the image sensing element. However, with the trend of thin and light digital imaging products, the height of the image module must be continuously reduced. When the image sensor or optical system receives a large angle of incident light source, the center wavelength of the reflective near-infrared filter glass will be large. The offset exceeds the white balance φ line of the image sensor, causing a color shift problem. Controlling the center wavelength shift of the near-infrared filter glass can solve this problem' when the incident angle of the light source is between 0 and 30. The T50% offset needs to be less than 5 nm. But this optical requirement has exceeded the reflective; the physical limit of the glass. The absorption near-infrared filter glass can solve the above problems, and the related art is disclosed in the Republic of China Invention Patent Publication No. 200920709 (hereinafter referred to as the 709 case).

The spectral characteristics of the 201200485 709 case are: under the thickness limit of 0.4~〇2, the transmittance of visible light of 4〇〇~5〇〇nm can reach 80~90% or more, and the medium read length (T5Q%) is controlled at 6QQ. In any band between ~65〇nm, the average infrared transmittance of 750~11〇〇nm is less than 3%. In the fiscal test month 'J' first placed on the two sides of the light glass on the anti-reflection film and placed under the specified temperature and humidity conditions (85〇c, 85/〇RH), continuous testing for 5 hours, no glass surface Rough or atomized. However, the quality and aging of digital imaging products are constantly being improved. In high-order or products that can be produced in harsh loops, the environmental conditions set by the weather resistance test are _ 赖 harsh, 嶋RH, miscellaneous office). In view of the demand for optical glass manufacturers, the manufacturer of the company should submit uncoated anti-reflective glass dies to the notarized test position for _ sex testing. It is known that the best resistance of wsm light glass picking performance is based on the two-part anti-reflection film, and the bare film cannot pass the test conditions of harsh environment. In view of this, the present case proposes a kind of fluorinated acid that has excellent resistance to anti-reflection film. The near-infrared ray-receiving type of light-receiving ray can be used in the above-mentioned high-order fields. Digital imaging products in the environment, whose polar weathering characteristics and aging performance can match the expected goals. SUMMARY OF THE INVENTION The main object of the present invention is to provide a fluorine-like salt 彡 Wei-type near-infrared light-emitting glass, which is made of a gas-wet salt-based composition and added with a light energy control additive. .

The t-light source (four) is between 〇~3(). Between, private outside the line of light glass 201200485 ‘. The wavelength (T50%) offset is less than 5 nm. And the glass in this case is tested for the financial performance by bare chip, and the continuous test under 60 C, 90% RH constant temperature environment has a spectral stability of at least 1 hrs. Therefore, the case is more suitable for imaging and High-grade, light-thin, long-term or polar applications in its related fields. The main technique for achieving the above object of the present invention comprises: forming a glass block by melting a raw material composition and cooling the molten raw material composition, and forming a glass bare piece after cutting, grinding, polishing, and the like, and forming a glass bare piece; The substance mainly includes p2〇5' A|F3, Cu〇, and gold φ is a fluoride.

SrF2 is 5 輭φ %~10 Μ %, BaF2 is 1〇wt %~15 wt %, and ZnF2 is 〇wt %~5wt %. [Embodiment] The fluorine-filled acid-based absorption type near-infrared filter glass is formed by melting a raw material composition and cooling the melted raw material composition to form a glass block, which is subjected to cutting, grinding, polishing, and the like. After the formation of the glass die. The raw material composition mainly includes P2〇5, AIF3, CU〇, and metal fluoride. The total content of P2〇5, AIF3, and CuO is preferably from 42% by weight to 755% by weight. The total content of metal fluorides R + F + R2 + F is preferably from 30% by weight to 60% by weight. More specifically, the individual addition amount of the composition: p2〇5 is 4〇^%~6〇^%; A|fr , 3 201200485 is 1 wt 〇/〇, wt 〇/〇; Cu〇 is! Wt 〇 / 〇 ~ 5 wt 〇 /. . The metal fluoride in the present embodiment 'R+F contains NaF 3 wt % to 10 wt %, LiF, KF' may optionally be added to the composition. The respective addition amounts of LiF are 〇 wt 〇 / 〇 ~ 5 wt %, and KF is 0 wt % ~ 1 〇 wt %. In the present embodiment, R2+F comprises MgF2 of 1 wt% to 5 wt%, CaF2 of 5 wt%~1〇wt 〇/〇, S "F25 wt%~1〇wt%, BaF210 wt. ~15 wt% and ZnF2 are 〜%~5wt 0/〇. In the above composition, P2〇5 is the main component of the fluorophosphate glass mesh structure chain, which has the function of lowering the refractive index and low dispersion rate of the glass. In the present embodiment, Cu is also used as a near-infrared absorbing agent. According to the experimental results, if the total content of P2〇5 is less than 4〇wt%, it will not achieve good near-infrared absorption effect with Cu〇, and the liquid phase of the glass. The temperature will increase. However, the total content of P2〇5 cannot be higher than 60 wt〇/〇, which will reduce the weather resistance of the glass and deteriorate the resistance to devitrification. Therefore, in this case, the total content of 'P2〇5 is 4〇wt%~ 60wt% is the preferred range. AIF3 in the case of the implementation of the _ acid glass swell resistance to devitrification and increase the glass viscosity of the main h 'AIF3 total content if less than 彳 will make Lai Linglin low, glass The rate of crystallization is increased, and the difficulty in forming the glass is increased. If the total content of the metal is higher than 1〇_%, the glass will be Choi devitrification is deteriorated, Wei glass melting difficult. Therefore, in the present case, the total content of Ah 1wt% ~1〇wt% range is preferred.

The offset needs to be less than Snm to prevent the image sensor from being out of color due to exceeding its white balance limit. Table 5 shows the fine-grained best-off s. For example, the gas sulphate filter glass has an incident angle of 0 to 30. The relationship between T50% offset and light transmittance. As can be seen from Tables 5-1, 5-2 and 3, the incident angle of the light source is between 〇3 and 3〇. The wavelength of 〇5〇% is controlled between 609 and 611nm, which meets the optical requirement that the above Τ5〇% offset is less than 5nm. _ Therefore, the problem of color shift of the image ❹jH due to exceeding the self-balancing limit can be avoided. Further, the average transmittance of visible light (400 to 500 nm) is between 8% and 89%, and the average transmittance of near-infrared rays (700 to 1100 nm) is less than 5%.
