Two camera lenses for 3D low light level color night vision systemare designed in CODE V. The panchromatic sensitive camera lens works in a widespectral band 400nm-1000nm, yellow green-sensitive camera lens works in a band of400nm-600nm.The two camera lenses have same parameters, such as focal length 120mm,relative aperture 1/2, the field angle of 5.26 °. In the design of two camera lenses,we split and complex cooke triplet lens, the chromatic aberration is balanced byadding a binary diffractive surface. The results of design show that sensitivepanchromatic camera lens and yellow-green-sensitive camera lens, in the all fieldof view, when the Nyquist frequency is 77.5 (lp / mm), all MTF is larger than 0.6;the axial chromatic aberration of sensitive panchromatic camera lens is 0.056mm.Two camera lenses have good imaging performance. © (2014) Trans Tech Publications, Switzerland.
