Abstract
An imaging system lens assembly includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element in order from an object side to an image side along an optical path. Each of the six lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The first lens element has positive refractive power. The fifth lens element has positive refractive power. The image-side surface of the fifth lens element is concave in a paraxial region thereof. The image-side surface of the sixth lens element has at least one inflection point. A central thickness of the first lens element is a maximum among central thicknesses of all lens elements of the imaging system lens assembly.
