Evaporating material and method of producing optical thin film utilizing the same. |
摘要 |
<p>An evaporation material is employed to form an optical thin film which is adapted to be formed on an optical element such as a lens or the like. The evaporation material is provided such that zirconium oxide (ZrO2) is mixed with a titanium oxide (TiOA) having a molar ratio A(O/Ti) of oxygen to titanium in a range of 1.0 to 1.75 so that the mixture assumes a molar ratio (Ti/Zr) of titanium to zirconium in a range of 1.0 to 4.0. The mixture is sintered or fused and solidified. <IMAGE></p> |
