The lens is composed of four lenses. It has a symmetric structure with positive and negative focal lengths. Its focal length, numerical aperture and field of view are 17.20 mm, 0.063 and 16.82° respectively. The lens operates in the waveband from 486 nm to 656 nm. Its total optical length is 68 mm. It has the maximum distortion of 1.13% in the full field of view and the modulation transfer function greater than 0.64 at a space frequency of 60 lp/mm. The design result shows that the system has good imaging quality and a compact structure which meet the practical requirements. %K optical design %K large filed of view %K CODE V %K compact system
