Abstract
An optical lens assembly includes, in order from the object side to the image side: a first lens with negative refractive power, a second lens with negative refractive power, a third lens with positive refractive power, a stop, a fourth lens with positive refractive power, a fifth lens with negative refractive power, a sixth lens with positive refractive power, and a seventh lens with negative refractive power, wherein a focal length of the first lens is f1, a focal length of the sixth lens is f6, and following condition is satisfied: −5.74<f1/f6<−1.83, which is favorable to reduce the impact of environmental temperature on the lens assembly and balance the distributing of the refractive power of the optical lens assembly, so as to correct the aberration and reduce the sensitivity.
