Abstract

A broadband infrared beam splitter (BS) on ZnSe substrate used for the spaceborne interferometric infrared sounder (SIIRS) is studied in the spectral range of 4.44-15 μm. Both broadband antireflection coating and broadband beam-splitter coating in this BS are designed and tested. To optimize the optical properties and the stability of the BS, suitable infrared materials were selected, and improved deposition techniques were applied. The designed structures matched experimental data well, and the properties of the BS met the application specification of SIIRS.

摘要

研究了一种用于星载干涉红外探测器（SIIRS）的、基于ZnSe衬底的宽带红外分束器（BS），其光谱范围为4.44 - 15μm。对该分束器中的宽带减反射涂层和宽带分束器涂层都进行了设计和测试。为优化分束器的光学性能和稳定性，选择了合适的红外材料，并采用了改进的沉积技术。设计的结构与实验数据匹配良好，分束器的性能满足SIIRS的应用规格要求。
