Abstract

This paper discussed the working principle of the LLL night vision(low-light level night vision)device and researched into the LLL night vision objective opjective optical system.An LLL night vision objective optical system with good image quality is finally got,which comes after debugging with the optical design software ZEMAX according to the theoretical calculation of the objective lens parameters specific to night vision system.
