Abstract

The invention provides visible light absorbing glass which comprises the following elements in mole percent: 0-10% of a manganese element, 0-5% of a chromium element; 0-3% of a nickel element, 0-3% ofa cobalt element, 0-3% of a vanadium element and 0-0.5% of a molybdenum element, wherein the sum of the mole percentages of the manganese, chromium, cobalt and vanadium elements is more than or equalto 5%. The invention also provides a preparation method and application of the visible light absorbing glass. The visible light absorption glass prepared by the method of the invention has higher light absorption effect in the range of 300-700 nm; and the transmittance of the visible light absorbing glass is less than or equal to 0.5% under the thickness of 0.20 mm. At the same time, the visiblelight absorbing glass is easy to melt and form, has no internal defects such as bubbles, caking, stripes and the like, has good devitrification resistance, moisture resistance and composition stability, and meets the preparation process requirements of optical fiber imaging elements in thermal performance.

Description

technical field [0001] The invention relates to the technical field of optical glass, in particular to a visible light absorbing glass with high absorption effect in the 300-700nm visible light band, a preparation method and application thereof. Background technique [0002] Light-absorbing glass is an important type of optical glass, which mainly realizes the absorption effect of interfering stray light and improves the clarity and contrast of optical components. The most typical applications are stray light absorption in fiber optic imaging components such as fiber optic faceplates, fiber optic inverters, fiber optic tapers, and fiber optic microlens arrays. With the expansion of application fields, the requirements for ultra-thin, high-definition, and high-contrast ratios have become higher and higher in recent years. Therefore, light-absorbing glass is required to have better light absorption effects and more thorough absorption of stray light. [0003] Ordinary light-a...
