Abstract
An optical imaging lens includes a first lens element having negative refracting power, a second lens element having negative refracting power and a periphery region of the image-side surface of the second lens element is concave, an optical axis region of the image-side surface of the fifth lens element is concave, an optical axis region of the image-side surface of the sixth lens element is concave. Lens elements included by the optical imaging lens are only six lens elements. υ1 is an Abbe number of the first lens element, υ3 is an Abbe number of the third lens element, EFL is an effective focal length, ImgH is an image height and Fno is a f-number to satisfy EFL*Fno/ImgH≤3.200 and υ1+υ3≤90.000.
