Abstract
An optical image capturing lenses includes, in order from an object side to an image side, a front lens group, a stop, and a rear lens group. The front lens group includes, in order from the object side to the image side, at least a first lens element and a second lens element. The first lens element has a convex object-side surface and a concave image-side surface. The rear lens group includes, in order from the object side to the image side, at least a third lens element, a fourth lens element, a fifth lens element, and a sixth lens element. The sixth lens element is made of plastic material. The object-side surface and the image-side surface of the sixth lens are aspheric. The sixth lens element has at least one inflection point formed on at least one of the object-side surface and the image-side surface thereof.
Claims8
An optical image capturing lenses comprising seven lens elements, the seven lens elements being, 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;
- wherein each of the seven lens elements comprises an object-side surface facing towards the object side and an image-side surface facing towards the image side;
- wherein the first lens element has positive refractive power, the sixth lens element has the image-side surface being concave in a paraxial region thereof, at least one of the object-side surface and the image-side surface of the sixth lens element is aspheric, the image-side surface of the sixth lens element comprises at least one inflection point, the seventh lens element has the image-side surface being concave in a paraxial region thereof, at least one of the object-side surface and the image-side surface of the seventh lens element is aspheric, and the image-side surface of the seventh lens element comprises at least one inflection point.
