視口 視鏡 美國A＆N公司 玻璃組件及室內樂配件

視口提供了一個簡單的方法，添加的觀察窗涂層系統(tǒng)和其他的應用程序所需要的真空室的內部視圖。 A&N manufactures viewports for high and ultra-high vacuum applications. A＆N生產高和超高真空應用視口。 When selecting a viewport for a specific pressure range, both flange style and window transition material must be considered.當選擇了一個視口，以便在特定的壓力范圍內，兩個凸緣的風格和窗口過渡材料必須加以考慮。 Kovar is used as the transition material on all ultra-high vacuum （UHV） applications.科瓦鐵鎳鈷合金被用作所有超高真空（UHV）應用程序上的過渡材料。 （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. （因為他們的窗口被釬焊在，視口使用科瓦鐵鎳鈷合金也被稱為固定窗口視口。）或者在高真空應用中用作過渡材料，彈性體密封件。 A&N weldable viewports use a replaceable, elastomer-sealed window and are therefore intended for high vacuum service. A＆N可焊視口中使用可更換的，彈性體密封的窗口，因此適用于高真空服務。 Standard window material is 7056 borosilicate glass.標準窗口材料是7056硼硅玻璃。 Quartz and sapphire windows are available on request.石英和藍寶石窗口可應要求提供。

Add-a-Doors serve as access points into your vacuum system.一門作為接入點到您的真空系統(tǒng)。 Viewport Add-a-Doors not only function as an access point into your system, but also provide a replaceable viewing window.視口外接一個門，不僅功能作為一個接入點到您的系統(tǒng)，而且還提供了可更換的觀察窗。
