Embodiment 1

[0057] like Figure 1 to Figure 20 As shown, the imaging lens group includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens with refractive powers in sequence from the light incident side to the light exit side, and the first lens includes: a first transmission surface , set on the outer circumference of the surface of the first lens close to the light-incident side; the first reflective surface, set on the outer circumference of the surface of the first lens close to the light-outside side; the second reflective surface, set on the first lens close to the light-incident side The optical axis of the surface; the second transmission surface is arranged on the optical axis of the surface of the first lens near the light-emitting side; wherein, the light enters the first lens from the first transmission surface, and is reflected to the second reflection surface through the first reflection surface , is reflected by the second reflective surface to the ...

Embodiment 2

[0075] like Figure 1 to Figure 20 As shown, the imaging lens group includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens with refractive powers in sequence from the light incident side to the light exit side, and the first lens includes: a first transmission surface , set on the outer circumference of the surface of the first lens close to the light-incident side; the first reflective surface, set on the outer circumference of the surface of the first lens close to the light-outside side; the second reflective surface, set on the first lens close to the light-incident side The optical axis of the surface; the second transmission surface is arranged on the optical axis of the surface of the first lens near the light-emitting side; wherein, the light enters the first lens from the first transmission surface, and is reflected to the second reflection surface through the first reflection surface , enter the second lens after being reflected from the ...

Abstract

The invention provides a camera lens group, and the camera lens group sequentially comprises a first lens to a fifth lens with focal power from a light incident side to a light emergent side, and the first lens comprises a first transmission surface which is arranged on the outer circumference of the surface, close to the light incident side, of the first lens; the first reflecting surface is arranged on the outer circumference of the surface, close to the light emitting side, of the first lens; the second reflecting surface is arranged on the optical axis of the surface, close to the incident side, of the first lens; the second transmission surface is arranged on the optical axis of the surface, close to the light-emitting side, of the first lens; light enters the first lens from the first transmission face, is reflected to the second reflection face through the first reflection face, is reflected to the second transmission face through the second reflection face and then enters the second lens. The effective focal length f of the camera lens group and the on-axis distance TTL from the surface, close to the light incident side, of the first lens to the imaging surface of the camera lens group satisfy f / TTLgt; and 1.5. According to the invention, the problem that long optical path and small size of the camera lens group in the prior art cannot be considered at the same time is solved.

Description

technical field [0001] The present invention relates to the technical field of optical imaging equipment, in particular to an imaging lens group. Background technique [0002] With the rapid development of science and technology and the improvement of people's living standards, mobile phones have become an inseparable electrical device in people's daily life, and the dependence on mobile phones has become stronger and stronger, resulting in people's need for mobile phones to take pictures in daily life. More and more, this has led to higher requirements for the portability and functionality of the camera lens in the market. Most of the traditional camera lenses are designed in sequence, and the camera lens on the mobile phone needs to meet the miniaturization requirements. If you want to increase the optical path of the camera lens, it will lead to an increase in the size of the camera lens, which is not conducive to It is assembled into the mobile phone, and is not conduci...
