Problems solved by technology

In terms of a six-element lens structure, in previous inventions, the distance from the object side of the first lens to the imaging surface on the optical axis is large, which is not conducive to the thinning of mobile phones and digital cameras
[0003] However, optical lens design does not simply reduce the proportion of a lens with good imaging quality to produce an optical lens with both image quality and miniaturization. The design process not only involves material characteristics, but also production and assembly yields. practical problems

Embodiment Construction

[0092] To further illustrate the various embodiments, the present invention is provided with accompanying drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments, and can explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these contents, those skilled in the art should understand other possible implementations and advantages of the present invention. Components in the figures are not drawn to scale, and similar component symbols are generally used to denote similar components.

[0093] The term "a lens has a positive refractive power (or negative refractive power)" in this specification refers to the positive (or negative) refractive power of the lens on the optical axis calculated by Gaussian optics theory. The image side and the object side are defined as the range through which the imaging ray passes, wherein the i...

Abstract

The present invention discloses an optical imaging lens. The optical imaging lens comprises in order from an object side to an image side a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens. The following conditional expressions are satisfied in that: TTL<=6.5mm; TL / (G23+G34+G45)<=2.7; or TTL<=6.5mm; TL / (G23+G34+G45)<=2.7; or TTL<=6.5mm; and TL / (G23+G34+G45)<=2.7. The optical imaging lens is configured for optics photography imaging and performs the control of the concave-convex curved surface arrangement of each lens and the control of the related parameters through adoption of at least two conditional expressions to shorten the length of the lens while maintaining good optical performance, increasing the effective focal length of the system and shortening the angle of the visual field.

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. ...
