Detailed Description
Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.
The following describes a lens 100 according to an embodiment of the present invention with reference to fig. 1 to 2, and the lens 100 may be applied to an electronic device.
As shown in fig. 1-2, a lens barrel 100 according to an embodiment of the present invention includes: a lens barrel 10, a plurality of lenses 20, and a first light blocking member 30.
As shown in fig. 1, one end of the lens barrel 10 close to the object side is an object side end 11, the lens barrel 10 has a first through hole 13, a plurality of lenses 20 are disposed in the lens barrel 10, each lens 20 includes an optical effective area 22 and a bearing area 23, the bearing area 23 surrounds the optical effective area 22, the bearing area 23 is mainly used for bearing and abutting, and the optical effective area 22 is mainly used for passing light.
As shown in fig. 1-2, the plurality of lenses 20 are disposed in the lens barrel 10, the lens 20 adjacent to the first through hole 13 in the plurality of lenses 20 is a first lens 21, the first light shielding member 30 is disposed between the lens barrel 10 and the first lens 21, the first light shielding member 30 covers the bearing area 23, the first light shielding member 30 is formed with a second through hole 31, wherein, in a plane perpendicular to the optical axis, a projection of the first light shielding member 30 on a projection cover side end 11 on the plane is projected on the plane. So that part of the light passing through the first through hole 13 will be blocked by the first light blocking member 30.
Specifically, when the first through hole 13 and the second through hole 31 are both circular holes, the aperture of the first through hole 13 is larger than that of the second through hole 31, that is, the edge of the second through hole 31 is located inside the edge of the first through hole 13, so that the first light shielding member 30 shields a part of incident light of the first through hole 13. That is to say, the first light shielding member 30 is added between the lens barrel 10 and the first lens 21 to serve as a diaphragm, the first light shielding member 30 is further provided with the second through hole 31, and the edge of the second through hole 31 is located inside the edge of the first through hole 13, so that the first light shielding member 30 can play a role in shielding a part of incident light, and stray light can be prevented from being presented on an image surface through the lens 20.
It can be understood that, as shown in fig. 1, the aperture of the second through hole 31 is a, and the aperture of the first through hole 13 of the lens barrel 10 is B, where a is less than B, so that after the light beam incident from the first through hole 13 is blocked by the first light-shielding member 11, a part of the light beam will be reflected onto the lens barrel 10, but after being reflected, the light beam cannot reach the image plane for imaging, thereby achieving the effect of eliminating stray light.
Therefore, according to the lens barrel 100 of the present invention, by adding the first light shielding member 30 between the first lens 21 and the lens barrel 10, the incident stray light can be effectively reduced, and the effect of eliminating the stray light can be achieved. In addition, by providing the first light shielding member 30, the requirement for the edge accuracy of the first through hole 13 of the lens barrel 10 is not required to be high, so that the difficulty in molding the lens barrel 10 can be reduced, and the cost of the lens 100 can be further reduced.
According to an optional embodiment of the present invention, a and B satisfy the relation: A/B is more than or equal to 0.2 and less than or equal to 0.8. The first through hole 13 and the second through hole 31 satisfying the above-mentioned relational expressions can effectively control light beams, and can adjust and improve the imaging effect of the lens 100.
Alternatively, as shown in fig. 2, the thickness of the first light shielding member 30 is C, the thickness of the lens barrel 10 at the first through hole 13 is D, that is, the thickness of the object side end 11 of the lens barrel 10 is D, where C and D satisfy the relation: C/D is more than or equal to 0.005 and less than or equal to 1. That is, the thickness of the first light-shielding member 30 is not more than the thickness of the object side end 11 of the lens barrel 10, and the thickness of the first light-shielding member 30 thus provided is appropriate to facilitate its arrangement at the first through hole 13 and to ensure its arrangement reliability at the object side end 11.
Wherein, the center of the first through hole 13 and the center of the second through hole 31 are located on the optical axis of the lens 100. Such an arrangement can further enhance the correspondence between the object-side end 11 and the first light-shielding member 30, which can be advantageous for receiving the incident light of the lens 100.
According to an alternative embodiment of the present invention, the cross section of the first through hole 13 may be circular or regular polygon. Due to the arrangement of the first light shielding member 30, the difficulty in molding the object side end 11 can be reduced, the processing precision of the lens barrel 10 can be improved, and the structural reliability of the lens 100 can be improved. When the cross section of the first through hole 13 is a regular polygon, the inner diameter of the first through hole 13 is the longest value of a line segment obtained by cutting the regular polygon through a line passing through the center of the regular polygon.
According to an alternative embodiment of the present invention, as shown in fig. 2, the edge of the second through hole 31 is configured in a truncated cone shape, and the cross section of the second through hole 31 is circular. The cross section of the second through hole 31 is designed to be circular, so that light can be conveniently and uniformly entered from the first through hole 13, the imaging effect of the lens 100 on an image plane is good, and the quality of the lens 100 is high.
Specifically, as shown in fig. 2, the cross-sectional area of the second through hole 31 tends to decrease in a direction approaching the first lens 21. The second through hole 31 thus arranged can facilitate its molding on the first light-shielding member 30 on the one hand, and can be beneficial to controlling the entering light on the other hand, so that the imaging effect of the lens 100 on the image plane is better, and the quality of the lens 100 is higher.
According to an alternative embodiment of the present invention, as shown in fig. 1, the first light shielding member 30 may be configured in a sheet shape, and a portion of the first light shielding member 30 is attached and fixed to the surface of the object side 11 near the first light shielding member 30. By forming the first light shielding member 30 into a sheet shape, the lens barrel 10 can be simplified in structure and easily molded, and the weight and cost of the lens barrel 10 can be reduced.
According to an alternative embodiment of the present invention, two adjacent lenses 100 are padded at the edge with a second light-shielding member 40 for eliminating veiling glare. The second light-shielding member 40 can further achieve the effect of eliminating stray light, and the quality of the lens 100 can be improved.
Specifically, the second light blocking member 40 may be a light blocking sheet. The gobo is thin, is suitable for being arranged between two adjacent lenses 20, and has simple manufacture and low cost.
As shown in fig. 1, a plurality of mounting steps 12 are formed in the lens barrel 10, and edges of a plurality of lenses 20 are disposed at the mounting steps 12. The mounting step 12 can fix the position of the lens 20, and can make the lens 20 more firm and reliable, so that the structural reliability of the lens 100 can be improved.
