| The development of new optical instruments with multiband detect function is researched by the diversification of war environment and the progress of camouflage technique. The multiband anti-reflection coating is produced for them. According to the practical needs, the design principle of the multiband anti-reflection coating based on graded-index is expounded and the elementary film structure using two materials with different refractive index is given in the thesis. Moreover, the influence of the film thickness and layer on optical characteristics is analyzed, and the coating is optimized by using the design software. A technical test for film of ZnS and YF3 was administered. Finally, considering the environment-resistant capability of the multiband anti-reflection coating, the result is educed. |
