本文描述保护水溶性光学系统在苛刻的环境条件下不受潮解损坏的一种简单方法。这种技术有助于保护在10.6微米波长范围内使用的氯化钠元件,而这种技术也适用于其它光谱区内的其它光学材料。保护层是由在感兴趣的波长上具有高透射的热塑薄膜组成。和 CO_2激光器辐射配合使
This article describes a simple way to protect water-soluble optical systems from deliquescence under harsh environmental conditions. This technique helps to protect sodium chloride components used in the 10.6-micron wavelength range, and this technique also applies to other optical materials in other spectral regions. The protective layer consists of a thermoplastic film that has a high transmission at the wavelength of interest. And CO 2 laser with the radiation
