3D-Printed Achromatic Metalens Brings Fiber Imaging Into Focus
JENA, Germany, Nov. 2, 2022 — Because light of different wavelengths is shaped and refracted differently, lenses located on the end faces of optical fibers can experience strong chromatic aberration. Chromatic aberration can lead to a shift in the focal point and blurred imaging over a range of wavelengths, hindering these lenses, which are used for applications that include endoscopy for medical diagnostics. To remedy these aberrations, an international research collaboration optimized an optical glass fiber so that
