OPTICAL LENS SYSTEMS, IMAGING UNITS AND ELECTRONIC EQUIPMENT

Abstract

The optical imaging lens system comprises eight lens elements which, in order from the object side to the image side along the optical path, are: the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element, the sixth lens element, the seventh lens element, and the eighth lens element. The sixth lens element has a convex image-side surface in its anti-axial region. The seventh lens element has positive refractive power and has a convex object-side surface in its anti-axial region and a concave image-side surface in its anti-axial region. The eighth lens element has negative refractive power and has a convex object-side surface in its anti-axial region and a concave image-side surface in its anti-axial region. The invention also relates to an imaging device and electronic equipment.
