Abstract
The utility model relates to optical field, concretely is a kind of traffic lens and imaging device, the traffic lens is sequentially composed of fixed lens group of positive focal power, focusing lens group of negative focal power and compensation lens group of positive focal power from object plane side to image plane side;The focusing lens group moves along the main optical axis direction of the traffic lens, for adjusting the object distance of the traffic lens;The traffic lens satisfies the following conditional formula:-4 The focal length of focusing lens group is reduced, the focal length of focusing lens group front group and rear group is optimized, the possibility of excessive volume of front group and rear group is reduced, the traffic lens has small change in resolving power, and the miniaturization of traffic lens is realized.
