Abstract
Provided is a near-infrared light absorbing glass with a near-infrared light absorbing element and a near-infrared light absorbing filter. When the length of the near-infrared light absorbing glass is 1 mm, transmissivity is more than 80% at the wavelength of 400 nm, and more than 85% at the wavelength of 500 nm. The near-infrared light absorbing glass contains P, Al, Li, Rand Curepresented by positive ions, wherein Rrepresents Mg, Ca, Srand Ba. Meanwhile, the near-infrared light absorbing glass contains Oand Frepresented by negative ions. Water durability (D) of the near-infrared light absorbing glass reaches Class 1 and acid durability (D) reaches above Class 4. In this invention, fluorphosphate glass is used as the matrix glass and the components are designed specially, so that the melting temperature of glass can be effectively lowered and the chemical stability of the glass can be excellent.
