High Numerical-Aperture Solarization-Resistant Silica-Glass Air-Cladding Fiber Bundle for the Ultraviolet Imaging
Year: 2025
Type: article
Abstract: We report the design, fabrication and characterization of a new type of air-cladding fiber bundle (ACFB) made of fused silica glass. By using of the stack-and-draw fabrication method, 5605 cores of ACFB are divided into 295 hexagonal subregions, each comprised of 19 cores and enclosed by thin silica struct. Up to 0.99 NA and 6.2 μm resolution are measured at selective wavelengths in the spectral range from 400 nm to 800 nm. The image delivery at 254 nm wavelength by ACFB is demonstrated. The imaging by ACFB made of pure fused silica glass presents no degradation after exposure to 300 Gy X-ray radiation.
