Embodiment Construction

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work all belong to the protection scope of the present invention.

[0039] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indications are only used to explain the position in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a telescopic three-group continuous zoom optical lens, an imaging assembly and a mobile phone. The telescopic three-group continuous zoom optical lens comprises a lens main body. The lens main body comprises a lens barrel, a zoom lens group and a compensation lens group; the zoom lens group comprises a first lens group with negative focal power and a second lens group with positive focal power, the compensation lens group comprises a third lens group with negative focal power, and the first lens group, the second lens group and the third lens group can move forwards and backwards; and the focal lengths of the first lens group, the second lens group and the third lens group are f1, f2 and f3, the distances between the first lens group and the second lens group at a wide-angle end and a telephoto end are dw12 and dt12, and the distances between the second lens group and the third lens group at the wide-angle end and the telephoto end are dw23 and dt23. The following relational expression is satisfied, the application of the lens main body to electronic equipment with relatively thin thickness, such as a mobile phone and the like, is facilitated.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a telescopic three-group continuous zoom optical lens, an imaging component and a mobile phone. Background technique [0002] With the continuous development of mobile phone camera lens related technologies, consumers have higher and higher performance requirements for mobile phone lenses. The traditional fixed-focus mobile phone lens with digital zoom solution can no longer meet the growing consumer demand. The continuous optical zoom lens has the ability to zoom continuously within a certain focal length range, and can achieve perfect imaging with different magnifications, so it has become the direction of major mobile phone lens manufacturers. However, the traditional continuous optical zoom lens solution cannot be directly transferred to mobile phones. The biggest obstacle lies in the lens volume. The thickness of a general smartphone is less than 10mm, while the lengt...
