To solve the spectral demand and material design conflicts of multifunctional coupling and integration of optical materials， a collaborative design method based on ［TiAlN/Ag］²/TiAlN sequential structure film for visible transmission induction and infrared radiation suppression is proposed， interpreting the new principles and mechanisms of multifunctional coupling of sequential structure film materials. Meanwhile， its optical compatibility performance is characterized. It shows that the ［TiAlN （thickness of 30 nm）/Ag （thickness of 15 nm）］ ²/TiAlN （thickness of 30 nm） sequential composite film has the optical characteristics of band-pass selective transmission and mid-far infrared low radiation， which can better realize the multifunctional compatibility effects of perspective， shading， low radiation temperature control， and infrared stealth， and can be used in the radiation temperature control and infrared stealth application fields of special glasses such as military vehicles and green buildings.
