| 摘要 |
The present invention is directed to an antireflection and UV rejection coating. The coating comprises at least eight layers wherein adjoining layers alternate between high (58) and low (57) refractive index materials. The layer (58) adjacent an article (40) on which the coating is formed has a high refractive index greater than about 330 nanometers. The index of refractive of the low refractive index material (57) is less than about 1.50 at a wavelength of about 520 nanometers. The two layers (57, 55) of low refractive index material nearest the article each have an optical thickness at a wavelength of about 330 nm of about one-quarter wavelength. |
