Abstract:
A wide angle lens module includes a first lens and a second lens with negative refracting power, a third lens and a fourth lens with positive refracting power, a fifth lens with negative refracting power, a sixth lens with positive refracting power, and a seventh lens with negative refracting power. The first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, and the seventh lens are disposed in order from an object side to an image side.

Abstract:
An exemplary imaging lens includes, in this order from the object side to the image side thereof, a first lens of positive refraction power, a second lens of negative refraction power, a third lens of positive refraction power, and a fourth lens of negative refraction power. The imaging lens satisfies the formulas of: (1) 0.5 R5>R7, where F1 is the focal length of the first lens, F is the effective focal length of the imaging lens, R5 is the radius of curvature of the object-side surface of the third lens, R6 is the radius of curvature of the image-side surface of the third lens, and R7 is the radius of curvature of the object-side surface of the fourth lens.
