Abstract
The utility model discloses an ultra-wide band antireflection-film lens. The ultra-wide band antireflection-film lens includes a substrate and a film layer covered on the surface of the substrate, wherein the film layer is obtained through superposing at least two film layers, wherein the odd-numberth film lays are magnesium fluoride layers, the even-numberth film lays are zirconium/titanium mixture film layers. According to the ultra-wide band antireflection-film lens of the utility model, magnesium fluoride is adopted as a low- refractive index material, and at the same time, a zirconium/titanium mixture is adopted as a high-refractive index material; the high-refractive index material is matched with the low- refractive index material so as to be plated for forming a multilayer film; and further the ultra-wide band antireflection-film lens is advantageous in strong adhesiveness of the film layers, high temperature resistant performance and structural simplicity, and has greater imaging effect than that of a lens which is combined by other materials.
