仿生蛾眼是一种具有抗反增透效果的微纳米结构, 该结构采用化学沉银方法制作了随机分布的双面仿生蛾眼抗反射纳米结构透镜, 平均透射率在97%以上。分析了相同参数组合条件下周期蛾眼结构和随机蛾眼结构的透射率情况, 得出在设计波段内, 随机蛾眼结构透射率优于周期结构的结论。采用蛾眼透镜进行相关参数的计算, 利用CODE V平台设计了一款全蛾眼成像镜头。该蛾眼系统焦距为25.5 mm, F数为5, 视场角13°, 光谱范围400～700 nm。经过成像对比试验显示, 蛾眼镜头相比常规镀膜镜头而言, 对鬼像、边缘眩光等杂散光具有很好的抑制作用。

Bionic moth-eye is a kind of micro-nano structure with anti-reflection ability. Random distributed double-sided bionic moth-eye antireflective nanoscale lens was manufactured by chemical precipitation silver method, with an average transmittance of over 97%. It could be concluded that the transmittance of random moth-eye structure was better than that of period structure at the design wavelengths by analyzing the transmittance of both period and random moth-eye structures under the conditions of the same parameter combinations. The moth-eye lens was used to calculate the related parameters, and a whole moth-eye imaging lens was designed by using CODE V platform. This moth-eye optical system has an effective focal length of 25.5 mm, an F-number of 5, a field of view of 13°, a spectral range of 400-700 nm. Compared with conventional coating lens, the moth-eye lens has a good inhibition effect on the ghosts, edge glare and other stray light by performing the imaging contrast test.
