At this point, it is necessary to set up the component to resist the internal force of the film surface, which can be a tubular metal frame, but also a thin film gas rib.

此时需要设置抵抗膜面内力的构件，该构件可以是管状的金属构架，也可是薄膜气肋，即：内充高压气体而具有一定抗弯刚度的管状。

Because the capacity of the optical component lies crucially on the thin film thickness, monitoring the deposition thickness becomes the key to the precise production.

光学薄膜的厚度对光学元件的性能有决定性的影响，因此精确控制膜厚就成为了关键。
