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.

Fiber optic image inverter with ultra-short twister, fabrication method therefor, application thereof, and related composition

A capillary array includes a capillary region, including capillaries of a first glass, which are disposed in an axis-parallel manner. A low refractive index layer is disposed on an inner wall of each of the capillaries, the refractive index of each low refractive index layer being less than a refractive index of a liquid scintillator. A second glass material is disposed between adjacent capillaries. A softening point of the first glass is T, a softening point of second glass is T, and a value of Tminus Tis in a range from 30° C. to 50° C. A thermal expansion coefficient of the first glass is α. An edge covering region is disposed on an outer side of the capillary region and makes contact with an outer side face of the capillary region, wherein a material of the edge covering region is a third glass.
