Abstract

The invention discloses an optical imaging lens. The optical imaging lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens along an optical axis from anobject side to an image side, wherein the first lens has a positive focal power, an object side surface of the first lens is a convex surface, an image side surface of the first lens is a concave surface, the second lens has a negative focal power, the third lens has a focal power, the fourth lens has a positive focal power, the fifth lens has a negative focal power, and the distance VP from an intersection point of a straight line where an edge light ray of the optical imaging lens is located and the optical axis to an axis of the object side surface of the first lens conforms to a conditionthat VP is more than 0 millimeter but less than 1.5 millimeters.

Description

technical field [0001] The present application relates to the field of optical elements, more specifically, to an optical imaging lens. Background technique [0002] In recent years, with the upgrading of consumer electronic products and the development of image software functions and video software functions on consumer electronic products, the market demand for optical imaging lenses suitable for portable electronic products has gradually increased. For example, the market demand for full-screen mobile phones continues to expand. [0003] In a full-screen mobile phone, the screen occupies a relatively large installation space of the mobile phone, which reduces the installation space of other accessories of the mobile phone. The installation space of the front camera is also increasingly restricted. In order to meet the demand for miniaturization and meet the imaging requirements, an optical imaging lens that can take into account miniaturization and small head size, good...
