Abstract

The invention discloses an optical imaging lens which sequentially comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens from an object side to an image side along an optical axis, wherein the first lens has focal power, the second lens has focal power, the third lens has negative focal power and the object side surface of the third lens is a convex surface, the fourth lens has focal power, and the fifth lens has negative focal power and the object side surface of the fifth lens is a convex surface. Half of the Simi-FOV of the maximum field angle of the optical imaging lens satisfies Simi-FOV >= 60 degrees. The spacing distance T34 between the third lens and the fourth lens on the optical axis and the central thickness CT5 of the fifth lens on the optical axissatisfy 1.5 < T34 / CT5 < 2.5.

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to an optical imaging lens. Background technique [0002] When many photographers are shooting large-scale scenes, such as tall mountain views, wide buildings, large parades, and all indoor exhibits, etc., they are often limited by aspects such as the field of view of the lens, so that the camera lens cannot Shoot a large area of ​​scenery. The angle of view of most camera lenses on the market is not enough to meet the needs of photographers for shooting large-scale scenes. [0003] Therefore, in order to meet the needs of more photographers for shooting large-area scenes, there is an urgent need in the market for an optical imaging lens that can take into account both high imaging quality and a large field of view. Contents of the invention [0004] One aspect of the present application provides such an optical imaging lens, the optical imaging lens includes in sequen...
