    摘要:

    可见/红外超宽光谱分色片是星载中分辨率光谱成像仪III 型光学系统中的重要光学薄膜器件。利用诱导透射原理,采用金属-介质膜系结构加非对称等效导纳匹配层,实现了45°入射时0.4-1.05mm光谱高效透射,1.35-13mm波段光谱高效反射,从而将入射光束分配到不同的光路。同时通过消偏振控制设计,获得了可见近红外波段低偏振灵敏度(LPS)。所研制的分色片可见近红外波段平均透射率大于85%,LPS小于4%;短波及长波红外波段平均反射率大于90%。

    Abstract:

    This paper describes the design and fabrication of one kind of dichroic beam-splitter that operates in an ultra-broadband spectral range from visible to longwave infrared regions simultaneously. The use of metal-dielectric coatings makes it implement structures that transmit the visible/near infrared radiation from 0.4 to 1.05mm and reflect infrared radiation from 1.36 to 13mm. At the same time, the structures are designed to obtain a low linear polarization sensitivity (Lps) in the visible/near infrared region. The transmission of visible/near infrared region is more than 85% and the average reflection of infrared region is more than 90%. The LPS of the region 0.4~1.05mm is less than 4%.
