在国际电报电话公司,我们利用溅射和蒸发等真空涂膜技术为美国军方研制成夜视装置。涂膜是个很复杂的过程,需要一系列精密操作,制备每种元件都要用到几种不同类型的真空系统,然后按严格的公差装成最终产品。除光学系统本身需要很特殊的膜层外,在利用可见光和红外光相互作用形成夜视像的光学元件之间还必须保持真空。此外,还需要一个真空系统来放置加工好的零部件以保护膜 At AT & T, we developed a night-vision device for the U.S. military using vacuum coating technology such as sputtering and evaporation. Coating is a complex process that requires a series of precision operations, preparing several different types of vacuum systems for each component and then packing them to the final product with tight tolerances. In addition to the optical system itself requiring a very special film layer, a vacuum must also be maintained between the optical elements that utilize the visible and infrared light to interact to form a night-vision image. In addition, a vacuum system is also required to place the finished parts to protect the film
