Example Embodiment

[0095] To further illustrate the various embodiments, the present invention is provided with drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments, and can cooperate with the relevant description in the specification to explain the operation principle of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the figure are not drawn to scale, and similar component symbols are usually used to indicate similar components.

[0096] In this specification, "a lens has a positive refractive power (or a negative refractive power)" refers to the positive (or negative) refractive power on the optical axis of the lens calculated by Gaussian optics theory. The image side and object side are defined as the range through which the imaging light passes. The imaging light inclu...

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 and a sixth lens, wherein the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens are sequentially arranged from an object side to an image side. The above six lenses satisfy the following conditional expression: TTL/AAG < = 4.1; 1.2 < = (T1 + T6)/ (T2 + T3 + T4). According to the technical scheme of the invention, through controlling the arrangement of the concavo-convex surfaces of all the above lenses and controlling related parameters according to at least two conditions, the good optical performance is maintained and the effective focal length of the system is increased. Meanwhile, the field angle of the lens is reduced and the length of the lens is shortened.

Description

technical field [0001] The present invention is related to an optical imaging lens, and especially an optical imaging lens using a six-piece lens. Background technique [0002] The specifications of consumer electronic products are changing with each passing day, and the pace of pursuit of lightness, thinness and compactness has not slowed down, and the demand for telephoto features has even begun to be added. Therefore, the specifications of key components of electronic products such as optical lenses must continue to improve in order to meet the needs of consumer electronics. needs of the reader. The most important characteristics of optical lenses are nothing more than image quality and volume. Among them, in terms of imaging quality, with the advancement of image sensing technology, consumers' requirements for imaging quality will also increase. Therefore, in the field of optical lens design, in addition to pursuing thinner lenses, lens imaging must also be considered. ...
