Visible and infrared control and guide system as one of controling means receives extensive attention increasingly in terms of military. In order to meet the requirements of infrared optical instruments, a visible and infrared triple waveband filter film system is designed according to the theory of thin film. Through the comparative study on serveral kinds of the common materials used in visible and infrared area, ZnS and YbF3 are selected as the materials. On the substrate of Ge, coating with average reflectance 91% at 450~950 nm while average transmittance 86% at 3.7~4.8 μm and 7.5~9.0 μm, eletron beam and ion assisted deposition technique is used in this process. More requirements are integrated into the coatings,and the structures of optical instruments can be simplified. Results of test show that all the parameters meet the requirements.
