摘要
由于可见近红外光学镜头用于宽波段（0．4～1．1μm），所以各透镜的加工及装校相比较其他适用于窄波段的透镜难度较大，为了保证整机的成像质量，必须提高系统加工装校的精度。这种透镜的加工装校精度应以某个透镜的像差权重为依据，利用每一个透镜的偏心对系统MTF的影响变化，对每个透镜进行分析校正，得出影响的大小，对每个透镜进行定心校正。
Due to the visible nearly infrared optical lens used in wide band （0.4 - 1.1 um）, the lens processing, assembly and correction is more difficult than other suitable for narrow band of the lens. In order to guarantee the machine imaging quality, the accuracy of the system＇s processing and assembling must be improved. According to a lens＇ aberration weight, lens processing accuracy should use the eccentricity of each lens to influence the change of system Modulation Transfer Function （MTF）. According to the analysis and correction of each lens, the mix and min of the influence are obtained, and centering correction for each lens is processed.
