硫化铅红外探测器可靠性研究

Reliability Research of PbS IR Detector

硫化铅红外探测器是用于航空航天、军事等高科技领域可探测1～3μm波长微弱红外辐射的光敏器件。通过对硫化铅红外探测器的设计和工艺研究，在理论分析和工艺试验的基础上，优化探测器光敏元制膜材料配方、改进光敏元保护工艺以及红外探测器装配工艺，解决了器件在特殊环境下使用的性能稳定性和可靠性问题。从而为研制高可靠性硫化铅红外探测器找到了有效的途径。

PbS IR detector is a kind of photosensitive detector which can dectect faint infrared ray with wavelength from 1-3 μm and can be used in high thch field such as space flight,military affairs and so on. Based on the principle of PbS IR detector design and the research of technological process,considering the theroy and the practice, filmmake materical prescription and protective technology of detector photosensitive unit and the assembly technology of IR detector are optimized. Meanwhile, stabilie and reliabilie use of the appliance in particular surraundings can be pledged. Qualified appliance of PbS IR detector is finally maufactured.
