摘　　要：　设计了550～1100nm波段高透、8000～12000nm波段高反的特宽光谱分光膜膜系,即采用|ZnS|Ag|ZnS|基本膜系结构,外加保护膜,并用该膜系镀制出了透可见、近红外波段,反中远红外波段的平面分光镜。实际使用表明,该膜系效果较好。A beam-splitting film system working in two ultra wide spectral ranges(high-transmissivity at 550～1100nm and high-reflectance at 8000～12000nm) is designed. The film system adopts a basic film structure of |ZnS|Ag|ZnS| with a protective coating. With the film system, we obtained a flat splitter which can transmit the visible and near-infrared bands, and reflect the middle-infrared and far-infrared bands. The actual application shows that the splitter is effective.
