Abstract
The present invention discloses a fabrication method and use of a Φ40 mm sized fiber optic image inverter, belonging to the field of manufacturing of fiber optic imaging elements. The light-absorbing glass for preparing the Φ40 mm sized fiber optic image inverter consists of the following components in molar percentage: SiO60-69.9, AlO1.0-10.0, BO10.1-15.0, NaO 1.0-8.0, KO 3.0-10.0, MgO 0.1-1.0, CaO 0.5-5.0, ZnO 0-0.1, TiO0-0.1, ZrO0.1-1.0, FeO3.0-6.5, CoO0.1-0.5, VO0.51-1.5 and MoO0.1-1.0. The Φ40 mm sized fiber optic image inverter has the advantages of low crosstalk of stray light, high resolution and high contrast.
