When the above relational expression is satisfied, the radius of curvature of the image side S10 of the fifth lens L5 at the optical axis O and the focal length of theoptical lens 100 can be controlled within a reasonable range, thereby helping to correct the astigmatism and field curvature of theoptical lens 100 and distortion, compress the total optical length of theoptical lens 100, and realize the design requirements of thinner and smalleroptical lens 100. When it is lower than the lower limit of the above-mentioned relational expression, the radius of curvature of the image side S10 of the fifth lens L5 at the optical axis O is too large, causing the surface shape of the fifth lens L5 to be too gentle, and it is difficult to fully correct the astigmatism of theoptical lens 100, Field curvature and distortion; when the upper limit of the above relational formula is exceeded, the radius of curvature of the image side S10 of the fifth lens L5 at the optical axis O is too small, resulting in an excessively large surface curvature of the fifth lens L5, and the addition of the fifth lens The sensitivity of L5 is not conducive to the engineering manufacture of the fifth lens L5.

When ΣET/ΣCT≥0.75, the optical path of the peripheral field of view of theoptical lens 100 is greater than the optical path of the central ray, which will cause the field curvature of theoptical lens 100 to be too large, causing blurred images in the outer field of view; when ΣET/ΣCT≤0.65 , the optical path of the peripheral field of view of theoptical lens 100 is shorter than the optical path of the central ray, which also easily causes the field curvature of theoptical lens 100 to be too large, resulting in blurred images in the outer field of view.

The air gap on the optical axis O. Specifically, AT23/AT12 can be 3.5, 5.6, 7.1, 9.4, 12.5, 16.7, 19.3, 22.6, 23.9, etc. When the above relational expression is satisfied, it is beneficial to converge the incident light rays and allow the light rays to smoothly transition to theimaging surface 101 . When AT23/AT12≥24, the air gap on the optical axis O from the image side S2 of the first lens L1 to the object side S3 of the second lens L2 is too small, and the distance between the image side S4 of the second lens L2 and the object side of the third lens L3 is too small. The air gap of the side S5 on the optical axis O is too large, which is not conducive to the convergence of the incident light, and it is easy to cause the light to be too steep in the space gap, which cannot smoothly transition to theimaging surface 101; when AT23/AT12≤3, the first lens The air gap between the image side S2 of L1 and the object side S3 of the second lens L2 on the optical axis O increases, and an additional spacer design is required, resulting in an increase in the weight and cost of theoptical lens 100, which is not conducive to theoptical lens 100. Miniaturization increases the difficulty of assembling theoptical lens 100 at the same time. The air gap on the optical axis O from the image side S4 of the second lens L2 to the object side S5 of the third lens L3 is compressed, which is not conducive to the smooth transition of light.

When TTL/f≤0.8, the total optical length of theoptical lens 100 is too short relative to the focal length of theoptical lens 100 , which easily increases the sensitivity of theoptical lens 100 and is not conducive to the convergence of light on theimaging surface 101 . When TTL/f≥0.9, the total optical length of theoptical lens 100 is too long relative to the focal length of theoptical lens 100, causing the chief ray angle of the light entering theimaging surface 101 to be too large, and the marginal light rays of theoptical lens 100 cannot be imaged on theimaging surface 101 Above all, the imaging information is incomplete, the imaging quality is reduced, and it is not conducive to realizing the miniaturization design of theoptical lens 100 .

When f1/R1≤1.55, the field angle range of theoptical lens 100 is too large, which increases the processing difficulty; when f1/R1≥1.80, the focal length of the first lens L1 does not match the curvature radius of the object side S1, resulting in the optical lens The imaging performance of 100 decreases and the amount of astigmatism increases.

一些实施例中,光学镜头100满足以下关系式:-14<R2/f1<-3。其中,R2为第一透镜L1的像侧面S2于光轴O处的曲率半径,f1为第一透镜L1的焦距。具体地,R2/f1可以为-13.9、-13.5、-10.0、-8.7、-6.5、-4.1、-3.5、-3.2或-3.05等。满足上述关系式时,有利于使得第一透镜L1物侧面S1的曲率半径、像侧面S2的曲率半径与第一透镜L1的焦距相适配,使得光学镜头100具备大视场的特性。R2/f1≤-14时,光学镜头100的视场角范围过大,增加加工难度;R1/f1≥-3时,第一透镜L1的焦距与像侧面S2的曲率半径不相适配,导致光学镜头100的成像性能下降,像散量增大。In some embodiments, theoptical lens 100 satisfies the following relationship: -14<R2/f1<-3. Wherein, R2 is the radius of curvature of the image side S2 of the first lens L1 at the optical axis O, and f1 is the focal length of the first lens L1. Specifically, R2/f1 may be -13.9, -13.5, -10.0, -8.7, -6.5, -4.1, -3.5, -3.2 or -3.05, etc. When the above relational expression is satisfied, it is beneficial to make the curvature radius of the object side S1 of the first lens L1 and the curvature radius of the image side S2 match the focal length of the first lens L1, so that theoptical lens 100 has the characteristic of a large field of view. When R2/f1≤-14, the field angle range of theoptical lens 100 is too large, which increases the difficulty of processing; when R1/f1≥-3, the focal length of the first lens L1 does not match the radius of curvature of the image side S2, resulting in The imaging performance of theoptical lens 100 decreases, and the amount of astigmatism increases.

Wherein, SAG41 is the distance from the intersection of the object side S7 of the fourth lens L4 and the optical axis O to the maximum effective radius of the object side S7 of the fourth lens L4 in a direction parallel to the optical axis O (that is, the object side of the fourth lens L4 Sagittal height of side S7), CT4 is the thickness of the fourth lens L4 on the optical axis O. Specifically, SAG41/CT4 can be -1.59, -1.43, -1.26, -1.10, -1.03, -0.95, -0.87, -0.79 or -0.71, etc. When the above relational expression is satisfied, the vector height of the object side S7 of the fourth lens L4 and the central thickness of the fourth lens L4 can be controlled within an appropriate range, so that the light transitions smoothly, which is conducive to making the imaging of the external field of view relatively brighter and improving the imaging quality , and at the same time facilitate the processing and molding of the fourth lens L4. When SAG41/CT4≤-1.6, the central thickness of the fourth lens L4 is too thin, and the object side S7 of the fourth lens L4 is too curved, which is not conducive to the processing and molding of the fourth lens L4, and reduces the molding yield; SAG41/CT4 When ≥-0.7, the curvature of the object side S7 of the fourth lens L4 is too small, it is difficult for the light to transition smoothly, and the relative brightness of the external field of view is too small, resulting in reduced image quality.

一些实施例中,光学镜头100满足以下关系式:-4<SAG42/MIN45<-0.4。其中,SAG42为第四透镜L4的像侧面S8与光轴O的交点至第四透镜L4的像侧面S8的最大有效半径处在平行于光轴O方向上的距离(即第四透镜L4的像侧面S8的矢高),MIN45为第四透镜L4的像侧面S8至第五透镜L5的物侧面S9在平行于光轴O的方向上的最小空气间隙。具体地,SAG42/MIN45可以为-3.9、-3.1、-2.6、-2.3、-1.7、-1.1、-0.6、-0.53、-0.49或-0.42等。满足上述关系式时,有利于校正光学镜头100的外视场畸变,提高光学镜头100的成像质量,同时有利于第四透镜L4的加工成型,提高生产良率。SAG42/MIN45≤-4时,第四透镜L4至第五透镜L5之间的空气间隙太薄,矫正畸变的空间有限,导致矫正效果不佳; SAG42/MIN45≥-0.4时,第四透镜L4的像侧面S8弯曲度与最小空气间隙配比不相适配,不利于畸变校正,同时光线难以平稳过渡,导致光学镜头100的成像质量降低。In some embodiments, theoptical lens 100 satisfies the following relationship: -4<SAG42/MIN45<-0.4. Wherein, SAG42 is the distance from the intersection of the image side S8 of the fourth lens L4 and the optical axis O to the maximum effective radius of the image side S8 of the fourth lens L4 in a direction parallel to the optical axis O (that is, the image of the fourth lens L4 Sagittal height of side S8), MIN45 is the minimum air gap in the direction parallel to the optical axis O from the image side S8 of the fourth lens L4 to the object side S9 of the fifth lens L5. Specifically, SAG42/MIN45 can be -3.9, -3.1, -2.6, -2.3, -1.7, -1.1, -0.6, -0.53, -0.49 or -0.42, etc. When the above relational expression is satisfied, it is beneficial to correct the distortion of the external field of view of theoptical lens 100 , improve the imaging quality of theoptical lens 100 , and at the same time facilitate the processing and molding of the fourth lens L4 and improve the production yield. When SAG42/MIN45≤-4, the air gap between the fourth lens L4 and the fifth lens L5 is too thin, the space for correcting distortion is limited, resulting in poor correction effect; when SAG42/MIN45≥-0.4, the fourth lens L4 The curvature of the image side S8 does not match the ratio of the minimum air gap, which is not conducive to distortion correction. At the same time, it is difficult for light to transition smoothly, resulting in a decrease in the imaging quality of theoptical lens 100 .
