利用组合套镀法布里珀罗结构光学薄膜滤光片间隔层的方法，选取锗和一氧化硅分别作为高低折射率膜层材料，在短波红外区域2.0～2.4 μm光谱范围内，设计并制备了8通道集成窄带滤光片，单个光谱通道的有效通光区域的宽度为450 μm，其间有30 μm的挡光过渡带。各通道的峰值光谱透射率大于65%，滤光片的半峰全宽为8～13 nm，相对带宽在0.33%～0.65%之间。

Using the method to combine masks and plating the spacer layer of the Fabry-Perot filter, germanium and silicon oxide are selected as the high and low index coating materials, 8-channel integrated filter is designed and fabricated with an effective light-transmitting width of 450 μm separated by a block of 30 μm for each channel in the spectral regions of 2.0～2.4 μm. For each channel, the maximum transmittance is greater than 65%, the full width at half maximum (FWHM) is 8～13 nm, as well as, the relative bandwidth is between 0.33%～0.65%.
