摘　　要：对于探测光谱特征,需要设计多光谱波段的光学镜头。根据设计需求,设计了一个基于声光可调滤波器选通晶体的多光谱镜头,该镜头采用变焦设计,以适应不同场景分辨率的使用要求,同时在设计的过程中,采用分段设计,对系统的出瞳和入瞳进行了优化匹配,并校正了色差,以及绘制出变焦曲线,为后期系统变焦制动方案提供了依据。In order to detect spectral characteristics, there is a need of designing multispectral bands optics. According to design requirements, the multispectral camera based on acousto-optic tunable filter （AOTF） gating crystal is designed. The zooming design is adopted so as to adapt the resolution requirements at different situations. During the design process, the segmented design is adopted, while the exit pupil and the entrance pupil of the system are matched optimally. The chromatic aberration is corrected and the zooming curve is plotted. All the above provides the basis for the zoom braking project of the future system.
