Abstract

The invention discloses an optical imaging lens. The optical imaging lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens, wherein thefirst lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens and the seventh lens are sequentially arranged from the object side to the image side along the optical axis; the first lens and the fifth lens are provided with positive focal power, and the image side surface of the first lens is a concave surface; the second lens, the third lens, the fourth lens, the sixth lens and the seventh lens are provided with focal power, and the image side surfaces of the second lens and the sixth lens are concave surfaces; the object side surface of the sixth lens is a convex surface; and the object side surface of the seventh lens is a concave surface. According to the optical imaging lens, the maximum half-field-of-view angle HFOV of the optical imaging lens and thetotal effective focal length f of the optical imaging lens satisfy tan (HFOV)* f >= 4.34 mm.

Description

technical field [0001] The present application relates to an optical imaging lens, and more particularly, to an optical imaging lens including seven lenses. Background technique [0002] In recent years, with the rapid development of portable electronic products, the pixels of mobile phones have increased rapidly, and mobile phones with a main camera with a pixel of up to 40 million pixels have appeared on the market. According to this development speed, it is imminent for manufacturers to design mobile phones with higher image quality. In theory, by increasing the number of lenses in the lens and using more lenses to balance various aberrations, the imaging quality of the lens can be greatly improved. However, if the number of lenses is not limited, the size of the lens will undoubtedly increase, which is contrary to the trend of continuous ultra-thinning of portable devices such as mobile phones. Therefore, how to design a lens with higher imaging quality, capable of mat...
