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.

Fabrication method and use of F40 mm large-size and high-contrast

The present application discloses a method for fabricating a fiber optic image inverter with an ultra-short twister. The method includes: drawing a glass rod with a low refractive index and a high strain point temperature into a surrounding pipe fiber; drawing a glass rod with a high refractive index and a high transmittance into a filling glass fiber, and then drawing into a casing pipe absorption fiber; uniformly surrounding an outer side of a cladding glass pipe with the surrounding pipe fiber, and matching a core glass rod and the cladding glass pipe to be drawn into a mono fiber; and then performing fabrication of a multi fiber, fabrication of a multi-multi fiber, heat press fusion and twisting operation in sequence. The fiber optic image inverter with an ultra-short twister with a high resolution and a high contrast and clear imaging is obtained and applied in a low-light-level image intensifier.
