在大多数的真空环境的科学试验中，多数都会用到光学器件，而在真空环境中，粒子的运动自由程非常大，一旦真空环境中存在粒子化（分子、离子、原子、粒子团）的工作物质或附带杂质，都会对光学元件造成污染从而破坏光学器件的特性，大大减小光学器件的使用寿命，本文主要提供一种装置和方法，可以确保光学器件的使用寿命，维持光学器件的自身特性。

The optical device was used in most of the experiments in vacuum environment, in which the particles's free path is very large. Once the particles(molecules, ions, atoms, groups) or impurities exist in vacuum environment, it will pollute the optical device and destroy its properties and then greatly reduce its service life. So, we invent a device and method to solve this phe-nomenon, to protect the properties of the optical device in the complex vacuum condition.
