Abstract
An optical lens set includes: a first, second, third, fourth, fifth, sixth and seventh lens element, said first lens element has positive refractive power, said second lens element has positive refractive power, said third lens element has negative refractive power, said sixth lens element has an object-side surface with a concave part in a vicinity of the optical axis, and said seventh lens element has an image-side surface with a concave part in a vicinity of the optical axis. The optical lens set does not include any lens element with refractive power other than said first, second, third, fourth, fifth, sixth and seventh lens elements. In addition, υ6 is the Abbe number of the sixth lens element, and the optical lens set satisfies the relationship: υ6≥50.
