摘要： Present embodiments provide for an optical imaging lens. The optical imaging lens includes a first lens element (110;210;310;410;510;610;710;810;910;10'10), a second lens element (120;220;320;420;520;620;720;820;920;10'20), a third lens element (130;230;330; 430;530;630;730;830;930;10'30), a fourth lens element (140;240;340;440;540;640;740;840;940; 10'40), a fifth lens element (150;250;350;450;550;650;750;850;950;10'50), a sixth lens element (160;260;360;460;560;660;760;860;960;10'60) and seven lens element (170;270;370;470;570; 670;770;870;970;10'70) positioned in an order from an object side (A1) to an image side (A2). Through the arrangement of convex or concave surfaces of the seven lens elements, the length of the optical imaging lens may be shortened while providing better optical characteristics and imaging quality.

摘要： An optical lens set (1) includes no air gap between the first lens element (10) and the second lens element (20), the third lens element (30) of a concave object-side surface near its optical-axis (4), and the sixth lens element (60) of a convex image-side surface near its periphery. The Abbe number υ3 of the third lens element (30) and the Abbe number υ5 of the fifth lens element (50) satisfy |υ3-υ5|≤25.
