Abstract

The invention provides an optical imaging lens. From the object side of the optical imaging lens to the image side of the optical imaging lens, the optical imaging lens sequentially comprises: a first lens, wherein thefirst lens has positive focal power, and the object side surface of the first lens is a convex surface; a second lens, wherein the second lens has negative focal power, and the image side surface of the second lens is a concave surface; a third lens, wherein the third lens has negative focal power, the object side surface of the third lens is a convex surface, and the image side surface of the third lens is a concave surface; a fourth lens, wherein the fourth lens has positive focal power; a fifth lens, wherein the fifth lens has focal power; and a sixth lens, wherein the sixth lens has negative focal power, the object side surface of the sixth lens is a concave surface, and the image side surface of the sixth lens is a concave surface. The effective focal length f of the optical imaging lens and the entrance pupil diameter EPD of the optical imaging lens meet the condition that f / EPD <1.9; and the maximum field angle FOV of the optical imaging lens meetS the condition that 0.5<tan(FOV) <1.5. The problem that in the prior art, an optical imaging lens is poor in imaging quality is solved.

Description

technical field [0001] The present invention relates to the technical field of optical imaging equipment, in particular to an optical imaging lens. Background technique [0002] With the development of mobile phone photography technology, mobile phone photography products are ubiquitous; mobile phone photography enthusiasts take and share pictures and video works through mobile phones every day and share them in their social circles; good photography works will be widely spread and shared in social circles; Therefore, whether it is possible to take pictures with a rich sense of hierarchy has become one of the important reference standards that mobile phone users pay attention to when purchasing mobile phones; so that major mobile phone manufacturers have carried out key planning and design on mobile phone shooting functions in the process of mobile phone design. At present, the imaging quality of the current optical imaging lens is poor, and the quality of the pictures taken...
