As the key component of the space infrared camera,the micro-multi-band filter is widely used.Because of the complicated process and the harsh working conditions of the detector,the filters often have many problems.In order to fully expose the defects of the filter in the ground phase and to address these problems and to reduce the risk of camera on-track work,a set of multi-band filter quality assessment method suitable for space infrared camera is proposed in this paper,which covers product appearance inspection,structure size test,surface shape detection,spectral performance test,film quality inspection,environmental test examination,mechanical test and examination and so on.The purpose of this paper is to evaluate the product quality of micro-multi-band filter comprehensively and accurately in the process of filter development,and to reduce the potential risk during the use of the product.
