Abstract: Based on the film system design of infrared bandpass filter for satellite, analyzes the effects of different spectral bandwith in earth sensor on absorption and transmitted of Ge substrate and PbTe cladding material,and on equivalent index of refraction and reflectance loss of filter film system.The result of the design is given.Best spectral bandwith of earth sensor for satellite is proposed.
