Abstract:
1. An image capturing lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface and a convex image-side surface, wherein the object-side surface and the image-side surface of the first lens element are aspheric; a second lens element with positive refractive power having a concave object-side surface and a convex image-side surface, wherein the object-side surface and the image-side surface of the second lens element are aspheric; and a third lens element with negative refractive power having a concave image-side surface in a paraxial region thereof, wherein the image-side surface of the third lens element has at least one convex shape in an off-axis region thereof, and an object-side surface and the image-side surface of the third lens element are aspheric; wherein the image capturing lens assembly has a total of three lens elements with refractive power and further includes a stop disposed between the first lens element and the second lens element, a focal length of the image capturing lens assembly is f, a focal length of the second lens element is f2, a focal length of the third lens element is f3, an axial distance between the stop and the image-side surface of the third lens element is SD, an axial distance between the object-side surface of the first lens element and the image-side surface of the third lens element is TD, a central thickness of the first lens element is CT1, a central thickness of the second lens element is CT2, an entrance pupil diameter of the image capturing lens assembly is EPD, and the following conditions are satisfied:
