IMPROVED QUALITY MULTI-SPECTRAL ZINC SULFIDE
PROBLEM TO BE SOLVED: To provide an improved quality multi-spectral water-clear zinc sulfide, which is substantially free of impurities that produce discoloration of the water-clear zinc sulfide and degrade its performance.SOLUTION: An inert foil is cleaned by acid cleaning method, and zinc sulfide is cleaned to reduce metal contaminants, thereby reducing the metal contaminants. The zinc sulfide is wrapped with the inert foil, and then is treated by an HIP process, thereby obtaining low scatter water-clear zinc sulfide comprising: forward scatter at 0.6328 μm, as measured in a half cone angle of 3 degrees from the direction of incident laser beam, of less than 3%/cm; and less than 100 ppm of metallic contaminants in the water-clear zinc sulfide, based on the water-clear zinc sulfide. Articles are also provided, such as a window, dome lens, beam splitter, IR camera and spectrophotometer, in which the low scatter water-clear zinc sulfide is used.SELECTED DRAWING: None
【課題】無色透明硫化亜鉛の変色を生じさせて性能を低下させる原因となる不純物を実質的に含まない、向上した品質の多スペクトル無色透明硫化亜鉛の提供。【解決手段】不活性ホイルを酸クリーニング方法でクリーニングし、かつ硫化亜鉛もクリーニングして金属汚染物質を低減させることにより、金属汚染物質が低減される。前記硫化亜鉛を前記不活性ホイルに包み、ＨＩＰプロセスで処理することによって得られる低散乱無色透明硫化亜鉛は、入射レーザービームの周り３度の半円錐角内において３％／ｃｍ未満の０．６３２８μｍでの前方散乱を含み、かつ無色透明硫化亜鉛中の金属汚染物質の量が無色透明硫化亜鉛の重量に基づいて１００ｐｐｍ未満である、低散乱無色透明硫化亜鉛。前記低散乱無色透明硫化亜鉛を使用した窓及びドームレンズ、ビームスプリッタ、ＩＲカメラ又は分光光度計の様な物品。【選択図】なし
