Description
Technical Field
The invention belongs to the technical field of optical imaging, and particularly relates to an optical system, a lens module and electronic equipment.
Background
In recent years, with the development of portable electronic devices such as smart phones and tablet computers and the popularity of network communities, more and more people like to take pictures or share pictures with others after self-shooting, and the demand for shooting angles is increasing. The wide-angle lens can enlarge the shooting visual field and shoot a panoramic or large-scene picture in a limited distance range.
However, due to the characteristics of large viewing angle and large relative aperture, the total length of the lens group is often long, and it is difficult to mount the lens group on an ultrathin electronic product. Meanwhile, with the development of the CMOS chip technology, the pixel size of the chip is smaller and smaller, the imaging quality requirement for the matched optical system is higher and higher, and it is difficult to meet the requirement of matching a high-pixel photosensitive chip.
Disclosure of Invention
The invention aims to provide an optical system which meets the requirements of miniaturization of the structure and large visual angle.
In order to realize the purpose of the invention, the invention provides the following technical scheme:
in a first aspect, the present invention provides an optical system, comprising, in order from an object side to an image side in an optical axis direction: the first lens is provided with negative focal power, the object side surface of the first lens at the optical axis is a concave surface, the object side surface of the first lens at the circumference is a convex surface, and the image side surface of the first lens is a concave surface; the second lens has positive focal power, the object side surface of the second lens is a convex surface, and the image side surface of the second lens is a convex surface; the third lens has negative focal power, and the image side surface of the third lens at the optical axis is a concave surface; the fourth lens has focal power, and the image side surface of the fourth lens at the optical axis is a convex surface; the fifth lens has focal power, the image side surface of the fifth lens at the optical axis is a concave surface, and at least one inflection point is arranged on the image side surface of the fifth lens at the optical axis. The optical system satisfies the following conditional expression: 1.1< tan ω/SD1< 1.8; wherein ω is a half of the maximum field angle of the optical system, and SD1 is the maximum effective half aperture of the object-side surface of the first lens; and 1.7< TL/ImgH < 2.2; wherein TL is a distance on an optical axis from an object side surface of the first lens to an image plane of the optical system, and ImgH is a half of a diagonal length of an effective pixel region of the optical system. Through the reasonable arrangement of the surface type and the focal power of each lens from the first lens to the fifth lens, the optical system is ensured to meet the requirements of miniaturization, high resolution and large visual angle. When the value of tan ω/SD1 is lower than the lower limit, the first lens aperture of the system becomes large, resulting in an increase in the size of the entire module; when the value of tan ω/SD1 is higher than the upper limit, the aperture of the first lens is compressed excessively, which is not favorable for light with a large angle of view to enter the camera lens. By reasonably setting the value of tan ω/SD1, the aperture of the first lens is not excessively increased while maintaining a wide angle of view, which is advantageous for system miniaturization. When the TL/ImgH value is higher than the upper limit, the system length is lengthened, so that the module height is increased; when the value of TL/ImgH is lower than the lower limit, the system is compressed excessively, aberration correction is not sufficient, and high resolving power is difficult to achieve. And a proper TL/ImgH ratio is set, so that the total length of the system can be compressed, and the ultra-thin design can be realized.
In one embodiment, the optical system satisfies the following conditional expression: -5< f5/f1< 7; wherein f1 is the effective focal length of the first lens, and f5 is the effective focal length of the fifth lens. The first lens with negative focal power is arranged, so that incident light rays with larger angles can enter the system, and wide angle is facilitated; meanwhile, the focal power of the fifth lens is reasonably configured, so that the sufficient back focal length can be ensured while the system aberration is corrected and the image quality is improved, the assembly and the matching of an electronic photosensitive element are facilitated, and the yield is improved. In one embodiment, the optical system satisfies the following conditional expression: 0.4< SD1/ImgH < 0.7. The ratio of SD1/I mgH is reasonably set, so that the system has a larger caliber to ensure the light flux, and the head of the system can not be excessively enlarged.
In one embodiment, the optical system satisfies the following conditional expression: 0.16< T12/OAL < 0.26; wherein T12 is an axial distance between an image-side surface of the first lens element and an object-side surface of the second lens element, and OAL is an axial distance between an object-side surface of the first lens element and an image-side surface of the fifth lens element. When the value of T12/OAL is lower than the lower limit, the air space of the lens is compressed, the shape of the first lens is insufficient, and the wide angle is not favorable; when the value of T12/OAL is higher than the upper limit, the system clearance is large and the ultra-thinning is insufficient. The value of T12/OAL is configured reasonably, the maximum field angle of the wide-angle lens group can be effectively increased. In one embodiment, the optical system satisfies the following conditional expression: -3< R1/R2<0, wherein R1 is the radius of curvature of the object side of the first lens and R2 is the radius of curvature of the image side of the first lens. The first lens is arranged in a double-concave shape at the position close to the optical axis, so that the first lens has negative focal power with sufficient strength, and wide angle is realized.
In one embodiment, the optical system satisfies the following conditional expression: -6< R3/R4< -2, wherein R3 is the object side radius of curvature of the second lens and R4 is the image side radius of curvature of the second lens. The second lens is arranged at the position close to the optical axis in a biconvex shape, so that light rays can be converged, and the shortening of the total length is realized.
In one embodiment, the optical system satisfies the following conditional expression: 2< (CT2+ CT3)/CT1< 4; wherein CT1 is a central thickness of the first lens element, CT2 is a central thickness of the second lens element, and CT3 is a central thickness of the third lens element. Through reasonable configuration of the thickness, the length of the lens can be further shortened, the first lens is easy to form, and the cost is reduced.
In one embodiment, the optical system satisfies the following conditional expression: V1/V5 is more than or equal to 1 and less than 2.5; wherein V1 is the Abbe number of the first lens and V5 is the Abbe number of the fifth lens. By reasonably setting the ratio of V1/V5, the chromatic aberration of the wide-angle lens can be reduced, and the resolution can be improved.
In one embodiment, the optical system satisfies the following conditional expression: -1 < f2/f3< 0; wherein f2 is the effective focal length of the second lens, and f3 is the effective focal length of the third lens. The second lens provides stronger positive focal power, which is beneficial to the ultrathin development of the wide-angle lens; the third lens provides negative focal power, so that aberration generated by the second lens can be corrected, and the resolving power is improved. Through the reasonable configuration of the focal length ratio of the two lenses, the optical system is facilitated to be ultrathin, meanwhile, the aberration generated by the second lens can be corrected, and the resolving power is improved.
In a second aspect, the present invention further provides a lens module, including a lens barrel and the optical system of any one of the first to the second aspects, wherein the first to the fifth lenses of the optical system are mounted in the lens barrel. By installing each lens of the optical system, the lens module can meet the characteristics of miniaturization and large-angle shooting.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The embodiment of the invention provides a lens module, which comprises a lens barrel and an optical system provided by the embodiment of the invention, wherein first to fifth lenses of the optical system are arranged in the lens barrel. The lens module can be an independent lens of a digital camera, and can also be an imaging module integrated on electronic equipment such as a smart phone. By installing each lens of the optical system, the lens module has the characteristics of miniaturization and large-angle shooting.
The embodiment of the invention also provides electronic equipment which comprises a shell, an electronic photosensitive element and the lens module provided by the embodiment of the invention, wherein the lens module and the electronic photosensitive element are arranged in the shell, and the electronic photosensitive element is arranged on an imaging surface of an optical system and is used for converting light rays of objects which penetrate through the first lens to the fifth lens and are incident on the electronic photosensitive element into electric signals of images. The electron sensor may be a Complementary Metal Oxide Semiconductor (CMOS) or a Charge-coupled Device (CCD). The electronic device can be a smart phone, a Personal Digital Assistant (PDA), a tablet computer, a smart watch, an unmanned aerial vehicle, an electronic book reader, a vehicle event data recorder, a wearable device and the like. By arranging the lens module, the electronic equipment can realize light weight, thinness and miniaturization, and can shoot in a large angle.
Embodiments of the present invention provide an optical system including, for example, five lenses, that is, a first lens, a second lens, a third lens, a fourth lens, and a fifth lens, which are disposed in order from an object side to an image side in an optical axis direction. Any adjacent two lenses among the first to fifth lenses may have an air space therebetween.
Specifically, the specific shape and structure of the five lenses are as follows:
the first lens has negative focal power, the object side surface of the first lens at the optical axis is a concave surface, the object side surface at the circumference is a convex surface, and the image side surface of the first lens is a concave surface. The second lens has positive focal power, the object side surface of the second lens is a convex surface, and the image side surface of the second lens is a convex surface. The third lens has negative focal power, and the image side surface of the third lens at the optical axis is a concave surface. The fourth lens has focal power, and the image side surface of the fourth lens at the optical axis is a convex surface. The fifth lens has focal power, the image side surface of the fifth lens at the optical axis is a concave surface, and at least one inflection point is arranged on the image side surface of the fifth lens at the optical axis.
The optical system further comprises a diaphragm, and the diaphragm can be arranged at any position between the first lens and the fifth lens, such as between the first lens and the second lens.
The optical system satisfies the following conditional expression:
1.1< tan ω/SD1< 1.8; where ω is half of the maximum angle of view of the optical system, and SD1 is the maximum effective half aperture of the object-side surface of the first lens. And
1.7< TL/ImgH < 2.2; wherein TL is a distance from an object side surface of the first lens element to an image plane of the optical system on an optical axis, and ImgH is a half of a diagonal length of an effective pixel region of the optical system.
The surface type and focal power of each lens from the first lens to the fifth lens are reasonably set, and the optical system is guaranteed to meet the requirements of miniaturization, high resolution and large visual angle. Meanwhile, the appropriate ratio of tan omega/SD 1 is set, so that the aperture of the first lens is not excessively increased while a wide viewing angle is maintained, and the system miniaturization is facilitated. The appropriate ratio of TL/ImgH is set, so that the total length of the optical system can be compressed, and the ultrathin design can be realized.
If tan omega/SD 1 is less than or equal to 1.1, the aperture of the first lens is enlarged, which results in an enlarged structure of the whole optical system, and if tan omega/SD 1 is more than or equal to 1.8, the aperture of the first lens is excessively compressed, which is not beneficial to the light with large visual angle entering the optical system.
If TL/ImgH is less than or equal to 1.7, the optical system is compressed excessively, the phase difference correction is insufficient, and higher resolving power is difficult to achieve. If TL/ImgH is not less than 2.2, the total length of the optical system becomes long, resulting in a large structure and difficulty in miniaturization.
In one embodiment, the optical system satisfies the following conditional expression: -5< f5/f1< 7; wherein f1 is the effective focal length of the first lens, and f5 is the effective focal length of the fifth lens. The first lens provides negative focal power, so that incident light rays with larger angles can enter the optical system, wide-angle design is facilitated, the focal power of the fifth lens is reasonably configured, system aberration is corrected, image quality is improved, sufficient back focal length can be guaranteed, assembly and matching of the electronic photosensitive element are facilitated, and yield is improved.
In one embodiment, the optical system satisfies the following conditional expression: 0.4< SD1/ImgH < 0.7; SD1 is the maximum effective half aperture of the object-side surface of the first lens; ImgH is half the length of the diagonal of the effective pixel area of the optical system. The optical system has larger caliber to ensure the light flux, and the head of the system can not be excessively enlarged.
In one embodiment, the optical system satisfies the following conditional expression: 0.16< T12/OAL < 0.26; wherein, T12 is the distance on the optical axis from the image-side surface of the first lens element to the object-side surface of the second lens element, and OAL is the distance on the optical axis from the object-side surface of the first lens element to the image-side surface of the fifth lens element. If T12/OAL is less than or equal to 0.16, the distance between the lenses is compressed, the shape of the first lens can not be effectively realized, and the design of wide visual angle is not facilitated, and if T12/OAL is more than or equal to 0.26, the optical system has large clearance, insufficient ultra-thinning and is not conducive to structure miniaturization. The value of T12/OAL is configured reasonably, the maximum field angle of the wide-angle lens group can be effectively increased.
In one embodiment, the optical system satisfies the following conditional expression: -3< R1/R2<0,
wherein R1 is the object-side radius of curvature of the first lens element, and R2 is the image-side radius of curvature of the first lens element. The first lens is arranged in a double-concave shape at the position close to the optical axis, so that the first lens has negative focal power with sufficient strength, and wide angle is realized.

The second lens is arranged at the position close to the optical axis in a biconvex shape, so that light rays can be converged, and the shortening of the total length is realized.
In one embodiment, the optical system satisfies the following conditional expression: 2< (CT2+ CT3)/CT1< 4; wherein CT1 is the central thickness of the first lens element, CT2 is the central thickness of the second lens element, and CT3 is the central thickness of the third lens element. When the thickness configuration is satisfied, the length of the optical system can be further shortened, the first lens is easier to form, and the cost is reduced.
In one embodiment, the optical system satisfies the following conditional expression: V1/V5 is more than or equal to 1 and less than 2.5; where V1 is the Abbe number of the first lens and V5 is the Abbe number of the fifth lens. When V1/V5 satisfies the above relation, the chromatic aberration of the optical system can be reduced, and the resolution can be improved.
In one embodiment, the optical system satisfies the following conditional expression: -1 < f2/f3< 0; wherein f2 is the effective focal length of the second lens, and f3 is the effective focal length of the third lens. The second lens provides stronger positive focal power, which is beneficial to the ultra-thin design of the optical system, and the third lens provides negative focal power, which can correct the aberration generated by the second lens and improve the resolving power.
