WebCrown vs Flint Glass. Crown glasses are optical glasses with low chromatic aberration (Abbe number above 55 or 50) which tend to have low refractive index. Many optical components such as lenses, mirror … WebCrown glasses tend to have better transmission in the NUV than do flint glasses. Flint glasses, because of their high index, feature higher Fresnel reflection loss and thus …

WebGlasses with an Abbe number of larger than 55, indicating low chromatic dispersion, are called crown glasses . They tentatively have a low refractive index. Glasses with Abbe numbers below 50 are called flint … WebGlasses with lower refractive indices and dispersions are designated as crowns, while those with higher refractive indices and dispersions are designated as flints. Modern crown glasses are based on silicate, phosphate, and borosilicate systems. WebJul 2, 2014 · In this paper, we present sequential atmospheric pressure plasma-assisted laser ablation of photovoltaic cover glass. First, glass samples were plasma pre-treated using a hydrogenous plasma process gas in order to accomplish a modification of the near-surface glass network by a chemical reduction and the implantation of hydrogen.
