Optical imaging lens

An optical imaging lens, from an object side to an image side in order along an optical axis comprising:

• 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, the first lens element to the sixth lens element each having an object-side surface facing toward the object side and allowing imaging rays to pass through as well as an image-side surface facing toward the image side and allowing the imaging rays to pass through, wherein:
• the third lens element has negative refracting power and a periphery region of the image-side surface of the third lens element is convex;
• an optical axis region of the image-side surface of the fourth lens element is convex;
• an optical axis region of the image-side surface of the fifth lens element is convex;
• and
• an optical axis region of the object-side surface of the sixth lens element is concave;
• wherein only the above-mentioned six lens elements of the optical imaging lens have refracting power;
• wherein, T1 is a thickness of the first lens element along the optical axis, T2 is a thickness of the second lens element along the optical axis, T4 is a thickness of the fourth lens element along the optical axis, G12 is an air gap between the first lens element and the second lens element along the optical axis, G34 is an air gap between the third lens element and the fourth lens element along the optical axis, G45 is an air gap between the fourth lens element and the fifth lens element along the optical axis, Abbe number of the second lens element is ν2, an Abbe number of the third lens element is ν3, an Abbe number of the fourth lens element is ν4 and an Abbe number of the sixth lens element is ν6, and the optical imaging lens satisfies the relationship:
• ν2+ν3+ν4+ν6≤130.000 and (T1+T4+G45)/(G12+T2+G34)≥2.500.
