Description

Technical Field

[0001] This invention relates to the field of zoom lens technology, and in particular to a large-image-size, large-aperture, wide-angle glass-plastic hybrid zoom lens and electronic device. Background Technology

[0002] A zoom lens is a lens that allows for adjustable focal length, enabling users to change the angle of view and imaging distance within a certain range. This design allows users to achieve different shooting effects without changing the lens itself. However, existing zoom lenses suffer from at least one of the following drawbacks:

[0003] 1) Currently, wide-angle dual-element zoom lenses on the market generally have a small image sensor size, typically less than 1 / 1.8” (9mm).

[0004] 2) Currently, even zoom lenses with a larger image size than 12.8mm are generally quite large and long, with some even exceeding 100mm in length.

[0005] 3) Due to the use of all-glass material, the lens may be relatively heavy and bulky.

[0006] 4) The manufacturing technology of all-glass lenses is relatively advanced, requiring the use of precision manufacturing equipment and processes, resulting in relatively high manufacturing costs. This may lead to a higher price for all-glass binary zoom lenses, making them unsuitable for all consumers.

[0007] 5) Some zoom lenses on the market may experience focus loss under high and low temperature conditions. Summary of the Invention

[0008] In view of this, the purpose of this invention is to provide a large-image-size, large-aperture, wide-angle glass-plastic hybrid zoom lens and electronic device. This lens has the following advantages:

[0009] 1. It has a large image plane, greater than 12.8mm (1 / 1.2”), and a relatively large aperture, with a short focal length aperture of 1.5.

[0010] 2. It features confocal light in the visible light range of 435-656nm and near-infrared light of 850nm, resulting in clear visible and night vision imaging without significant purple fringing.

[0011] 3. While possessing a large image plane, it has a short total optical length, which is less than 54mm.

[0012] 4. Using a glass-plastic hybrid solution results in a lighter weight compared to an all-glass solution of the same quantity.

[0013] 5. Using a hybrid glass-plastic solution results in lower costs compared to an all-glass solution with the same amount of glass.

[0014] 6. Using a glass-plastic hybrid solution, and considering the thermal design of the system, clear imaging can be achieved under high and low temperature conditions.

[0015] According to one aspect of the present invention, a large-aperture, wide-angle glass-plastic hybrid zoom lens is provided, wherein the lens comprises, from the object side to the image side, a negative optical power compensation group and a positive optical power zoom group.

[0016] During zooming from short focal length to long focal length, the zoom group moves away from the image plane along the optical axis, while the compensation group moves closer to the image plane along the optical axis; among which...

[0017] At the short focal length position, the interval between the zoom group and the compensation group is the largest, and the distance between the zoom group and the target surface is the smallest.

[0018] At the telephoto position, the interval between the zoom group and the compensation group is the smallest, and the distance between the zoom group and the target surface is the largest at this time.

[0019] The compensation group consists of a first lens, a second lens, a third lens, and a fourth lens.

[0020] The zoom group consists of a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens, a tenth lens, an eleventh lens, and a twelfth lens; the zoom group contains at least three plastic lenses.

[0021] In the above technical solution, the present invention has a large image plane, greater than 12.8mm (1 / 1.2”), and a relatively large aperture, with a short focal length aperture of f / 1.5; the present invention has confocal coverage of visible light 435-656nm and near-infrared light 850nm, resulting in clear visible and night vision imaging. The zoom group is the main part of the lens that changes the focal length. When zooming from a short focal length (wide-angle) to a long focal length (telephoto), the zoom group moves away from the image plane along the optical axis, which increases the focal length of the lens, making distant objects appear larger. However, aberrations that may occur during the movement of the zoom group, such as spherical aberration and chromatic aberration, are compensated for by the movement of a compensation group to maintain image quality. The aberrations introduced by the zoom group are further addressed by maintaining a consistent aperture size throughout the zoom range due to the fixed aperture stop position. This helps achieve similar depth of field and exposure at different focal lengths. Even at the telephoto end, a minimum center spacing is maintained, which helps avoid mechanical interference or collisions at extreme zoom positions. The negative optical power of the first compensation group effectively corrects aberrations that may be introduced by the zoom group, such as spherical aberration and chromatic aberration, thus maintaining image quality throughout the zoom range. The optical powers of the compensation group and the zoom group cancel each other out, reducing overall optical distortion of the system. Structurally, this design allows for a large zoom ratio, enabling users to make extensive adjustments between short and long focal lengths.

[0022] In some embodiments, the lens, from the object side to the image side, is as follows:

[0023] The first lens has negative refractive power, with a convex object-side surface and a concave image-side surface;

[0024] The second lens has negative refractive power, with a convex object-side surface and a concave image-side surface;

[0025] The third lens has negative refractive power, with a concave object side and a convex image side.

[0026] The fourth lens has positive refractive power, and the object-side surface is convex; the image-side surface is either flat or convex.

[0027] Aperture;

[0028] The fifth lens has positive refractive power, and the object-side surface is convex; the image-side surface is also convex.

[0029] The sixth lens has a convex object-side surface and a concave image-side surface.

[0030] The seventh lens has negative refractive power, with a convex object-side surface and a concave image-side surface;

[0031] The eighth lens has positive refractive power, and the object-side surface is convex; the image-side surface is also convex.

[0032] The ninth lens has negative refractive power, with a flat object-side surface and a concave image-side surface;

[0033] The tenth lens has positive refractive power, and the object-side surface is convex; the image-side surface is also convex.

[0034] The eleventh lens has negative refractive power, and the object-side surface is concave; the image-side surface is also concave.

[0035] The twelfth lens has positive refractive power, with a convex object-side surface and a concave image-side surface.

[0036] In the above technical solution, the first group is the compensation group, and the second group is the zoom group; from left to right, they are the compensation group for negative optical power and the zoom group for positive optical power. The aperture stop is located between the first and second groups, and its distance from the image plane remains fixed. The distance from the compensation group to the aperture stop is d1, the distance from the aperture stop to the zoom group is d2, and the distance from the zoom group to the image plane is d3. The values ​​of d1, d2, and d3 change as the system zooms. During the zooming process of the two-element zoom lens, when the lens changes from a short focal length to a long focal length, the zoom group moves away from the image plane, and the compensation group moves closer to the image plane, that is, the zoom group and the compensation group move closer together. During the zooming process of the two-element zoom lens, the distance between the zoom group and the compensation group is the largest at the short focal length position, and the distance between the zoom group and the target plane is the smallest at this time; the distance between the zoom group and the compensation group is the smallest at the long focal length position, but a certain minimum center distance is still maintained, and the distance between the zoom group and the target plane is the largest at this time.

[0037] In some embodiments, the second lens is a glass aspherical lens; the fifth lens is a glass aspherical lens; the sixth lens is a plastic aspherical lens with a small refractive power; the eleventh lens is a plastic aspherical lens; and the twelfth lens is a plastic aspherical lens.

[0038] The aforementioned technical solution utilizes aspherical design to effectively correct optical aberrations, helping to minimize spherical aberration, coma, astigmatism, and distortion in the optical system. This significantly improves image quality and reduces system size and weight. The invention employs a glass-plastic hybrid design, which is lighter and less expensive than an all-glass design with the same amount of material. Furthermore, the invention considers a heat-free system design, and the glass-plastic hybrid design allows the lens to produce clear images under both high and low temperature conditions.

[0039] In some embodiments, the lens satisfies the following condition:

[0040] |Φ6|<0.005;φ 11 <-0.03; φ 12 >0.015

[0041] In the formula, Φ6 is the optical power of the sixth lens, and φ 11 The optical power of the eleventh lens is φ. 12 The optical power of the twelfth lens.

[0042] In the aforementioned technical solution, this glass-plastic hybrid optical system employs three plastic aspherical lenses. Since the dn / dT (temperature refractive index coefficient) of plastic material is more than 10 times that of glass, an odd number of plastic aspherical lenses was chosen. In this configuration, one plastic aspherical lens is designed with an optical power close to zero to reduce its contribution to the system's thermal drift. The other two plastic aspherical lenses have opposite signs of optical power, which can, to some extent, cancel each other out temperature-induced changes in optical performance. This design utilizes the characteristics of aspherical lenses to optimize the temperature stability of the entire optical system. Furthermore, through precise system design and material selection, including thermal compensation measures for spacers and the base, excellent image quality can be maintained throughout the entire temperature range.

[0043] In some embodiments, the third lens, the fourth lens, the fifth lens, the eighth lens, and the tenth lens use aberrant dispersion glass material; the seventh lens and the eighth lens are cemented together to form a first cemented lens group; and the ninth lens and the tenth lens are cemented together to form a second cemented lens group.

[0044] In the above technical solution, the third lens, the fourth lens, the fifth lens, the eighth lens, and the tenth lens use aberrant dispersion glass material, which, together with the first cemented lens group and the second cemented lens group, is beneficial for correcting chromatic aberration.

[0045] In some embodiments, the lens satisfies the following condition:

[0046] |Vd7-Vd8|>40;|Vd9-Vd 10 |>40

[0047] Where Vd7 is the dispersion coefficient of the seventh lens, Vd8 is the dispersion coefficient of the eighth lens, Vd9 is the dispersion coefficient of the ninth lens, and Vd... 10 This is the dispersion coefficient of the tenth lens.

[0048] In the aforementioned technical solution, particular attention is paid to chromatic aberration correction. To this end, a cemented lens technique is employed, combining a positive lens and a negative lens to ensure that the difference in the dispersion coefficients of the two lens materials is greater than 40. This design strategy significantly improves the chromatic aberration correction capability, thus achieving better chromatic aberration correction results in cemented lenses. Furthermore, the design fully considers the confocal performance of visible and infrared light, ensuring good imaging results across both spectral ranges. Chromatic aberration at ultraviolet wavelengths is controlled, avoiding purple fringing that occurs in actual shooting, thereby guaranteeing image quality.

[0049] In some embodiments, the lens satisfies the following condition:

[0050] TTL≤54mm; C≥12.8mm; 1.5≤F≤2.9

[0051] In the formula, TTL is the total optical length of the lens, C is the diameter of the imaging ring of the lens, and F is the relative aperture.

[0052] In the above technical solution, the lens of the present invention has a large image plane while having a short total optical length, within 54mm. It has an aperture of F / 1.5-F / 2.9, high image quality, an imaging range ≥φ12.8mm, and is suitable for 1 / 1.2″ CCD or CMOS chips. The overall structure is compact, small in size, highly practical, and extremely convenient to install and use.

[0053] In some embodiments, the third lens and the fourth lens are made of anomalous dispersion materials;

[0054] The lens satisfies the following condition:

[0055] 1.70 <nd1<1.80;50<vd1<60;1.50<nd2<1.60;50<vd2<70

[0056] 1.45 < nd3 < 1.60; 80 < vd3 < 90; 1.90 < nd4 < 2.00; 17 < vd4 < 30 where nd1 is the refractive index of the first lens, vd1 is the dispersion coefficient of the first lens, nd2 is the refractive index of the second lens, vd2 is the dispersion coefficient of the second lens, nd3 is the refractive index of the third lens, vd3 is the dispersion coefficient of the third lens, nd4 is the refractive index of the fourth lens, and vd4 is the dispersion coefficient of the fourth lens.

[0057] In the above technical solution, for the third and fourth lenses, using an anomalous dispersion material is of great help in achieving a confocal effect for both short focal length and long focal length. Anomalous dispersion materials have dispersion characteristics different from those of conventional optical glasses, which enables them to more effectively correct chromatic aberration, especially at different wavelengths. By precisely controlling the refractive index (nd) and dispersion coefficient (vd) of each lens, an optical system can be designed that provides good imaging performance across the entire visible spectrum.

[0058] In some embodiments, the lens satisfies the following conditional expressions:

[0059] 1.45 < nd5 < 1.60; 80 < vd5 < 90; 1.60 < nd6 < 1.70; 18 < vd6 < 30

[0060] 1.60 < nd7 < 1.70; 30 < vd7 < 40; 1.40 < nd8 < 1.60; 80 < vd8 < 96

[0061] 1.70 < nd9 < 1.90; 40 < vd9 < 50; 1.40 < nd 10 < 1.60; 80 < vd 10 < 96 where nd5 is the refractive index of the fifth lens, vd5 is the dispersion coefficient of the fifth lens, nd6 is the refractive index of the sixth lens, vd6 is the dispersion coefficient of the sixth lens, nd7 is the refractive index of the seventh lens, vd7 is the dispersion coefficient of the seventh lens, nd8 is the refractive index of the eighth lens, vd8 is the dispersion coefficient of the eighth lens, nd9 is the refractive index of the ninth lens, vd9 is the dispersion coefficient of the ninth lens, nd 10 is the refractive index of the tenth lens, vd <##DEL_SPACE## 10 is the dispersion coefficient of the tenth lens.

[0062] In the above technical solution, by selecting the refractive index and dispersion coefficient ranges of different lenses, effective correction of chromatic aberration and optimization of imaging quality are achieved, while ensuring high-performance performance of the optical system across different spectral ranges.

[0063] According to another aspect of the present invention, an electronic device is provided, comprising the aforementioned large-image-size, large-aperture, wide-angle glass-plastic hybrid zoom lens; and

[0064] An image sensor is configured to receive images formed by the large-aperture wide-angle glass-plastic hybrid zoom lens.

[0065] In the above technical solution, the advantage of this electronic device relies on a large image area, large aperture, wide-angle glass-plastic hybrid zoom lens, which will not be elaborated here. Attached Figure Description

[0074] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the invention. Similarly, the following embodiments are only some, not all, embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0075] The purpose of this invention is to provide a large-image-size, large-aperture, wide-angle glass-plastic hybrid zoom lens and electronic device with high optical performance. Embodiments according to the invention will now be described in detail with reference to the accompanying drawings.

Figure 2 , Figure 8 , Figure 14 Figures 21 and 27 are telephoto cross-sectional views of the large-image-plane, large-aperture, wide-angle glass-plastic hybrid zoom lenses (optical systems) according to Examples 1 to 5. The large-image-plane, large-aperture, wide-angle glass-plastic hybrid zoom lenses according to the various examples are used in imaging devices including digital video cameras, digital still cameras, broadcast cameras, surveillance cameras, etc., and in optical devices with interchangeable lenses. In each cross-sectional view, the left side is the object-side OBJ and the right side is the image-side IMA. In each cross-sectional view, Lij represents the j-th lens of the i-th lens unit. ST represents the aperture stop (fixed aperture stop or visible aperture stop), OA represents the optical axis, and IMA represents the image plane. When the large-image-plane, large-aperture, wide-angle glass-plastic hybrid zoom lenses 1 to 5 according to the various examples are used in imaging optical systems for digital video cameras or digital still cameras, solid-state imaging elements (photoelectric conversion elements), such as CMOS image sensors or CCD image sensors, are arranged on the image plane IMA.

[0077] Based on the examples of large-aperture, wide-angle hybrid zoom lenses with large image planes and large apertures, a two-element zoom system is used. The first element is the compensation group L1, and the second element is the zoom group L2. The elements are arranged in order from the object side to the image side: from the object side to the image side, the compensation group L1 has negative optical power, and the zoom group L2 has positive optical power. The aperture stop ST is located between the first and second elements, and its distance from the image plane remains fixed. The distance from the compensation group to the aperture stop is d1, the distance from the aperture stop to the zoom group is d2, and the distance from the zoom group to the image plane is d3. The values ​​of d1, d2, and d3 change as the system zooms. The combined focal length of the lens is 5.85–13.8 mm, the zoom ratio is 2.36, the diagonal field of view (DFOV) is 134°–52°, and the relative aperture is 1 / 1.5–1 / 2.9. It has high imaging quality, is compatible with 1 / 1.2″ CCD or CMOS chips, has a compact overall structure, small size, strong practicality, and is extremely convenient to install and use.

[0078] During zooming from short focal length to long focal length, zoom group L2 moves along optical axis OA in the direction away from image plane IMA by direction B, and compensation group L1 moves along optical axis OA in the direction closer to image plane IMA by direction A.

[0079] At the short focal length position, the interval between zoom group L2 and compensation group L1 is the largest, and the distance between zoom group L2 and image plane IMA is the smallest; at the long focal length position, the interval between zoom group L2 and compensation group L1 is the smallest, and the distance between zoom group L2 and image plane IMA is the largest.

[0080] The compensation group L1 is composed of a first lens L11, a second lens L12, a third lens L13, and a fourth lens L14.

[0081] The zoom group L2 is composed of a fifth lens L21, a sixth lens L22, a seventh lens L23, an eighth lens L24, a ninth lens L25, a tenth lens L26, an eleventh lens L27, and a twelfth lens L28; the zoom group L2 contains at least three plastic lenses.

[0082] The lenses, from object side to image side, are as follows: First lens L11 has negative refractive power, with a convex object side and a concave image side; Second lens L12 has negative refractive power, with a convex object side and a concave image side; Third lens L13 has negative refractive power, with a concave object side and a convex image side; Fourth lens L14 has positive refractive power, with a convex object side and a flat or convex image side; Aperture ST; Fifth lens L21 has positive refractive power, with a convex object side and a convex image side; Sixth lens L22 has a convex object side and a flat or convex image side; The object-side surface is concave; the seventh lens L23 has negative refractive power, the object-side surface is convex, and the image-side surface is concave; the eighth lens L24 has positive refractive power, the object-side surface is convex, and the image-side surface is convex; the ninth lens L25 has negative refractive power, the object-side surface is flat, and the image-side surface is concave; the tenth lens L26 has positive refractive power, the object-side surface is convex, and the image-side surface is convex; the eleventh lens L27 has negative refractive power, the object-side surface is concave, and the image-side surface is concave; the twelfth lens L28 has positive refractive power, the object-side surface is convex, and the image-side surface is concave; protective lens G.

[0083] The second lens L12 is a glass aspherical lens; the fifth lens L21 is a glass aspherical lens; the sixth lens L22 is a plastic aspherical lens with a small refractive power; the eleventh lens L27 is a plastic aspherical lens; and the twelfth lens L28 is a plastic aspherical lens.

[0084] Among them, the seventh lens L23 and the eighth lens L24 are cemented together to form the first cemented lens group C1; the ninth lens L25 and the tenth lens L26 are cemented together to form the second cemented lens group C2.

[0085] According to the examples, the large-image-size, large-aperture, wide-angle hybrid zoom lens can satisfy at least one of the following settings 1) to 5):

[0086] 1) |Φ6|<0.005; φ 11 <-0.03; φ 12 >0.015;

[0087] 2) |Vd7-Vd8|>40;|Vd9-Vd 10 |>40;

[0088] 3)TTL≤54mm; C≥12.8mm; 1.5≤F≤2.9;

[0089] 4) 1.70 <nd1<1.80;50<vd1<60;1.50<nd2<1.60;50<vd2<70;1.45<nd3<1.60;

[0090] 80 <vd3<90;1.90<nd4<2.00;17<vd4<30;

[0091] 5) 1.45 <nd5<1.60;80<vd5<90;1.60<nd6<1.70;18<vd6<30;1.60<nd7<1.70;

[0092] 30 <vd7<40;1.40<nd8<1.60;80<vd8<96;1.70<nd9<1.90;40<vd9<50;

[0093] 1.40 <nd 10 <1.60; 80 <vd 10 <96;

[0094] In the above conditional expression, Φ6 is the optical power of the sixth lens, and φ 11 The optical power of the eleventh lens is φ. 12 Vd7 is the optical power of the twelfth lens; Vd8 is the dispersion coefficient of the seventh lens; Vd9 is the dispersion coefficient of the eighth lens; Vd is the dispersion coefficient of the ninth lens; Vd... 10 nd1 is the dispersion coefficient of the tenth lens; TTL is the total optical length of the lens; C is the image circle diameter of the lens; F is the relative aperture; nd1 is the refractive index of the first lens; vd1 is the dispersion coefficient of the first lens; nd2 is the refractive index of the second lens; vd2 is the dispersion coefficient of the second lens; nd3 is the refractive index of the third lens; vd3 is the dispersion coefficient of the third lens; nd4 is the refractive index of the fourth lens; vd4 is the dispersion coefficient of the fourth lens; nd5 is the refractive index of the fifth lens; vd5 is the dispersion coefficient of the fifth lens; nd6 is the refractive index of the sixth lens; vd6 is the dispersion coefficient of the sixth lens; nd7 is the refractive index of the seventh lens; vd7 is the dispersion coefficient of the seventh lens; nd8 is the refractive index of the eighth lens; vd8 is the dispersion coefficient of the eighth lens; nd9 is the refractive index of the ninth lens; vd9 is the dispersion coefficient of the ninth lens; nd 10 Let vd be the refractive index of the tenth lens. 10 The dispersion coefficient of the tenth lens is given.

[0095] Condition 1) defines the optical power of the sixth, eleventh, and twelfth lenses. By appropriately setting these conditions, the temperature drift of the entire optical system is kept within a reasonable range, allowing for compensation with the spacers and base, ultimately ensuring good image quality under both high and low temperature conditions. If the optical power of the sixth lens exceeds the upper limit, it may increase the system's temperature drift, affecting imaging stability. If the optical power of the eleventh lens exceeds the upper limit, it may reduce the system's chromatic aberration correction capability. If the optical power of the twelfth lens is below the lower limit, it may reduce the system's zoom range, limiting optical performance. The above settings ensure that the temperature drift is within an acceptable range while maintaining image quality, and are compatible with the thermal compensation capabilities of the spacers and base to achieve optimal performance under high and low temperature conditions.

[0096] Condition 2) defines the difference between the dispersion coefficients of the seventh and eighth lenses, and the difference between the dispersion coefficients of the ninth and tenth lenses. By appropriately setting the conditions, the difference between the dispersion coefficients of the positive and negative lenses is greater than 40. This allows for better chromatic aberration correction when the positive and negative lenses are cemented together. While ensuring good confocal performance in the visible and infrared ranges, it also ensures that the chromatic aberration in the violet wavelength range is not excessive. This prevents purple fringing in actual shooting. If the two differences are below the lower limit, the expected chromatic aberration correction effect may not be achieved, leading to purple fringing. The above settings ensure sufficient dispersion difference between the positive and negative lenses to achieve effective chromatic aberration correction. A more preferable setting ensures good confocal performance in both the visible and infrared ranges while controlling the chromatic aberration in the violet wavelength range.

[0097] Condition 3) defines the lens's overall optical length, image circle diameter, and relative aperture. With appropriate settings, the overall optical length is kept within 54mm. An aperture of F / 1.5-F / 2.9 ensures the lens's compactness and practicality while maintaining high image quality. An imaging range ≥ φ12.8mm, suitable for 1 / 1.2″ CCD or CMOS chips, ensures the lens's applicability and flexibility. These settings achieve a compact structure without sacrificing imaging performance. Simultaneously, they maximize the image plane size while keeping the overall optical length and relative aperture within optimal ranges.

[0098] Condition 4) defines the refractive index and dispersion coefficient of the compensation group lens. By appropriately setting the conditions, the lens can balance parameters for chromatic aberration correction and temperature stability. It can also work in conjunction with other parameters of the entire optical system to achieve optimal performance.

[0099] Condition 5) defines the refractive index and dispersion coefficient of the first six lenses in the zoom group. By appropriately setting the conditions, the parameters that meet the above settings can guarantee image quality during zooming. More preferably, the parameters can be set to match the dynamic performance of the zoom mechanism to achieve a smooth zooming effect. If the refractive index and dispersion coefficient of the eight lenses are higher than the upper limit, it may affect the image quality during zooming. If they are lower than the lower limit, the required zoom range and imaging performance may not be achieved.

[0100] A detailed description of the zoom lens based on each example will now be given.

[0101] Please refer to the optical structure of Example 1. Figure 1 and Figure 2 The specific parameters for Example 1 are shown in Tables 1, 2, and 3 below. In Example 1, the conditional expressions are as follows:
