Two camera lenses for 3D low light level color night vision system are designed in CODE V. The panchromatic sensitive camera lens works in a wide spectral band 400nm-1000nm, yellow green-sensitive camera lens works in a band of 400nm-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 by adding a binary diffractive surface. The results of design show that sensitive panchromatic camera lens and yellow-green-sensitive camera lens, in the all field of 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.

Two experiments were run comparing the operational binoculars AN/PVS-5 Night Vision Goggles with two monocular low cost night vision goggles using newer light intensification techniques. No decrement in performance was noted in visual acuity or depth perception with the monocular low cost goggles; an improved capability was noted with the new goggles in low light level conditions.
