Abstract: The irradiation-resistant fiber optic panels can be widely used in industrial X-ray detection and medical amorphous silicon flat panel detectors, etc. The fiber optic panels currently under development are difficult to accurately regulate the transmittance rate of the light-absorbing glass in the wavelength range of 430~900 nm, in addition to the poor resistance to precipitation performance. This paper focuses on the effects of glass coloring components on the transmittance and anti-decrystallization performance of light-absorbing glass and develops light-absorbing glass with excellent absorption effect at ultraviolet-visible-near-infrared wavelength and good anti-decrystallization performance. The results show that after adjusting the introduction amount of light-absorbing glass, the transmittance of irradiation-resistant fiber optic panels can reach more than 74%. When the spatial frequency is 10 lp/mm, the modulation transfer function (MTF) of panels with 2.0% (mass fraction) and 2.4% light-absorbing glass is still very obvious, and it can satisfy the requirements of irradiation-resistant optical fiber panels for the transmittance and MTF. This work solves the problems of insufficient resolution, low contrast, and poor imaging quality of irradiation-resistant fiber optic panels in the fields of medical treatment, industrial flaw detection, and space exploration, and realizes the localization of high-resolution, high-contrast, and high-quality irradiation-resistant fiber optic panels.
