Abstract
An optical imaging lens includes a first lens element to a fourth lens element, and each lens element has an object-side surface and an image-side surface. The first lens element has negative refracting power, an optical axis region of the object-side surface of the first lens element is convex, the third lens element has negative refracting power, and an optical axis region of the image-side surface of the fourth lens element is convex. Lens elements included by the optical imaging lens are only the four lens elements described above, and the optical imaging lens satisfies the relationship of Tmax+Tmin≤700.000 μm, Tmax is a maximum thickness of the four lens elements from the first lens element to the fourth lens element along the optical axis, Tmin is a minimum thickness of the four lens elements from the first lens element to the fourth lens element along the optical axis.
