视口提供了一个简单的方法，添加的观察窗涂层系统和其他的应用程序所需要的真空室的内部视图。 A&N manufactures viewports for high and ultra-high vacuum applications. A＆N生产高和超高真空应用视口。 When selecting a viewport for a specific pressure range, both flange style and window transition material must be considered.当选择了一个视口，以便在特定的压力范围内，两个凸缘的风格和窗口过渡材料必须加以考虑。 Kovar is used as the transition material on all ultra-high vacuum （UHV） applications.科瓦铁镍钴合金被用作所有超高真空（UHV）应用程序上的过渡材料。 （Because their windows are brazed in place, viewports using Kovar are also called fixed window viewports.） Alternatively, elastomer seals are used as the transition material in high vacuum applications. （因为他们的窗口被钎焊在，视口使用科瓦铁镍钴合金也被称为固定窗口视口。）或者在高真空应用中用作过渡材料，弹性体密封件。 A&N weldable viewports use a replaceable, elastomer-sealed window and are therefore intended for high vacuum service. A＆N可焊视口中使用可更换的，弹性体密封的窗口，因此适用于高真空服务。 Standard window material is 7056 borosilicate glass.标准窗口材料是7056硼硅玻璃。 Quartz and sapphire windows are available on request.石英和蓝宝石窗口可应要求提供。

Add-a-Doors serve as access points into your vacuum system.一门作为接入点到您的真空系统。 Viewport Add-a-Doors not only function as an access point into your system, but also provide a replaceable viewing window.视口外接一个门，不仅功能作为一个接入点到您的系统，而且还提供了可更换的观察窗。
