The vacuum compatible AJS170-0.5H-NL-V6 low outgassing adjustment screws are designed for demanding 1x10-6 Torr vacuum environments. Several key steps are taken in the design, assembly and packaging of these parts. We incorporate metals into our designs that are known to be vacuum compatible and desired or approved for use in vacuum systems. In particular, bronze is used in place of brass to virtually eliminate the presence of zinc, which will actually sublimate in a vacuum environment. Following the machining of the screw and bushing, each component is chemically cleaned in an ultrasonic bath to remove contaminating substances. Assembly is done in a cleanroom environment where lubrications that have recorded vacuum compatibility test data are used. Finally the adjustment screws are packaged in specially-cleaned vacuum-sealed bags, ready for cleanroom and vacuum chamber applications. The AJS170-0.5H-NL-V6 has precision cut 170-TPI threads for exceptionally fine adjustment sensitivity. It offers 0.5 inch (12.7 mm) precision travel obtained with hex-head adjustment, ideal for use with Newport optical mounts, stages, and most micrometer-compatible components. The standard 0.375 in. (9.5 mm) diameter collet is threaded with a nut for mounting to optical mounts and stages.


与真空兼容的AJS170-0.5H-NL-V6低放气调节螺丝适用于1x10-6 Torr真空环境。在这些零件的设计、装配和包装中采取了几个关键步骤。我们将金属融入我们的设计中，这些设计被认为是真空兼容的，并且在真空系统中被期望或批准使用。特别是用青铜代替黄铜，实际上是为了消除锌的存在，而锌实际上是在真空环境中升华的。在螺丝和衬套加工完成后，每个部件都要在超声波浴中进行化学清洗，以清除污染物质。在洁净室环境中进行组装，使用记录了真空相容性测试数据的润滑油。最后，调整螺丝被包装在特别清洁的真空密封袋中，可用于洁净室和真空室。AJS170-0.5H-NL-V6精密切割170-TPI螺纹，调节灵敏度极高。它提供了0.5英寸(12.7毫米)精度旅行获得与六角头调整，理想的使用与新港光学安装，舞台，和大多数微米兼容组件。标准的0.375英寸。(9.5毫米)直径夹头螺纹与螺母，用于安装到光学安装和阶段。
