大家知道,由(SiO/Ge)、(ZnS/Ge)、(ZnS/Te)和(ZnS/PbTe)等膜堆之一组成的窄带滤光片,在蒸发制备和使用过程中存在有两个方面的缺点: 1.膜层较软,一般不能擦拭,有时还会出现脱膜。2.窄带滤光片难于通过温度实验的检查。特别是在温度较大环境中使用时,滤光片的光学特性要变坏。由于存在上述缺点,使红外窄带滤光片应用条件受到限制。为此我们采用八十年代的新
It is known that there are two narrowband filters composed of one of the (SiO / Ge), (ZnS / Ge), (ZnS / Te) and (ZnS / PbTe) film stacks during evaporation preparation and use Aspects of the shortcomings: 1. The film is relatively soft, generally can not be wiped, and sometimes there will be stripping. Narrowband filters are difficult to pass the temperature test. Especially when used in a temperature environment, the optical properties of the filter deteriorate. Due to the above shortcomings, the application conditions of infrared narrow-band filters are limited. To this end, we use the new eighties
