Abstract

The invention discloses an optical imaging lens which sequentially comprises a first lens having positive focal power, a second lens having focal power, a third lens having focal power, a fourth lenshaving focal power, a fifth lens having focal power, a sixth lens having focal power, and a seventh lens having negative focal power from the object side to the image side along the optical axis, andthe image side surface of the fifth lens is a concave surface; the effective focal length f of the optical imaging lens and the maximum half-field angle HFOV of the optical imaging lens satisfy 5.5 mm< tan (HFOV) * f < 6.5 mm. The optical imaging lens has at least one beneficial effect of large image surface, large wide angle, large aperture, ultrathin property and the like.

Description

technical field [0001] The present application relates to an optical imaging lens, and more specifically, to an optical imaging lens including seven lenses. Background technique [0002] With the recent vigorous development of the smart phone field, major smart phone manufacturers have put forward more new demands for mobile phone lenses. Especially on the main camera of high-end flagship models, there is an increasing trend of mobile phone imaging lenses to develop toward larger image area, larger wide-angle, larger aperture, and ultra-thin, which poses more difficult challenges to optical system design . [0003] Compared with the previous mobile phone lens, the changes of these main value parameters have greatly improved the imaging capability and competitive advantage of the mobile phone lens. Large image area means higher resolution; large wide angle means larger field of view; large aperture means more effective light flux and higher signal-to-noise ratio; ultra-thin...
