Patent attributes
An image lens assembly system includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element. The first lens element has refractive power. The second lens element has positive refractive power. The third lens element has refractive power. The fourth lens element has refractive power. The fifth lens element has refractive power. The sixth lens element with refractive power is made of plastic material, and has at least one surface being aspheric. The seventh lens element with refractive power is made of plastic material and has a concave image-side surface, wherein the image-side surface thereof changes from concave in a paraxial region thereof to convex in a peripheral region thereof, and at least one surface thereof is aspheric.
