Camera optical lens

TECHNICAL FIELD

BACKGROUND

With the emergence of smart phones in recent years, the demand for a miniature camera lens is continuously increasing, but in general, photosensitive devices of a camera lens are nothing more than a Charge Coupled Device (CCD) or a Complementary Metal-Oxide Semiconductor Sensor (CMOS sensor), and as progress of semiconductor manufacturing technology makes a pixel size of the photosensitive devices become smaller, in addition, a current development trend of electronic products requires better performance with thinner and smaller dimensions, miniature camera lenses with good imaging quality therefore have become a mainstream in the market.

In order to obtain better imaging quality, a camera lens traditionally equipped in a camera of a mobile phone generally constitutes three or four lenses. Moreover, with development of technology and increase in diversified requirements of users, a camera lens constituted by five, six or seven lenses gradually appears in camera design, in case that a pixel area of the photosensitive device is continuously reduced and requirements on imaging quality is continuously increased. Although the common camera lens constituted by six lenses has good optical performances, its configuration such as refractive power, lens spacing and lens shape still need to be optimized, therefore the camera lens may not meet design requirements for some optical performances such as large aperture, ultra-thinness and wide angle while maintaining good imaging quality.

Here, k denotes a conic coefficient, and A4, A6, A8, A10, A12, A14, A16, A18, and A20 denote an aspherical coefficient, respectively.

y=(x²/R)/{1+[1−(k+1)(x²/R²)]^1/2}+A4x⁴+A6x⁶+A8x⁸+A10x¹⁰+A12x¹²+A14x¹⁴+A16x¹⁶+A18x¹⁸+A20x²⁰ (1)

Here, x denotes a vertical distance between a point on an aspherical curve and the optical axis, and y denotes a depth of the aspherical surface, i.e., a vertical distance between a point on the aspherical surface having a distance x from the optical axis and a tangent plane tangent to a vertex on an aspherical optical axis.

For convenience, the aspherical surface of each lens surface uses the aspherical surface shown in the above formula (1). However, the present invention is not limited to the aspherical polynomial form shown in the formula (1).

Design data of the inflection point and the arrest point of each lens in the camera optical lens 10 according to Embodiment 1 of the present invention are shown in Tables 3 and 4. Here, P1R1 and P1R2 denote the object side surface and image side surface of the first lens L1, respectively. P2R1 and P2R2 denote the object side surface and image side surface of the second lens L2, respectively. P3R1 and P3R2 denote the object side surface and image side surface of the third lens L3, respectively. P4R1 and P4R2 denote the object side surface and image side surface of the fourth lens L4, respectively. P5R1 and P5R2 denote the object side surface and image side surface of the fifth lens L5, respectively. P6R1 and P6R2 denote the object side surface and image side surface of the sixth lens L6, respectively. Data in an “inflection point position” column are a vertical distance from an inflexion point provided on a surface of each lens to the optical axis of the camera optical lens 10. Data in an “arrest point position” column are a vertical distance from an arrest point provided on the surface of each lens to the optical axis of the camera optical lens 10.

FIG. 2 and FIG. 3 are schematic diagrams of a longitudinal aberration and a lateral color of the camera optical lens 10 after light having a wavelength of 650 nm, 610 nm, 555 nm, 510 nm, and 470 nm passes through the camera optical lens 10 according to Embodiment 1, respectively. FIG. 4 is a schematic diagram of a field curvature and a distortion of the camera optical lens 10 after light having a wavelength of 555 nm passes through the camera optical lens 10 according to Embodiment 1. A field curvature S in FIG. 4 is a field curvature in a sagittal direction, and T is a field curvature in a meridian direction.

Table 17 below shows numerical values corresponding to various numerical values in Embodiments 1, 2, 3 and 4 and parameters specified in the conditions.

As shown in Table 17, Embodiment 1 satisfies various conditions.

In this embodiment, an entrance pupil diameter ENPD of the camera optical lens 10 is 0.743 mm, a full-field image height IH is 2.297 mm, and a field of view FOV in a diagonal direction is 120.00°. The camera optical lens 10 satisfies design requirements for large aperture, wide angle and ultra-thinness. The on-axis and off-axis chromatic aberrations are fully corrected, thereby achieving excellent optical performances.

FIG. 10 and FIG. 11 are schematic diagrams of a longitudinal aberration and a lateral color after light having a wavelength of 650 nm, 610 nm, 555 nm, 510 nm, and 470 nm passes through the camera optical lens 30 according to Embodiment 3. FIG. 12 is a schematic diagram of a field curvature and a distortion of the camera optical lens 30 after light having a wavelength of 555 nm passes through the camera optical lens 30 according to Embodiment 3.

Table 17 below shows numerical values corresponding to each condition in this embodiment according to the above conditions. It is appreciated that, the cameral optical lens 30 in this embodiment satisfies the above conditions.

In this embodiment, an entrance pupil diameter ENPD of the camera optical lens 30 is 0.813 mm, a full-field image height IH is 2.297 mm, and a field of view FOV in a diagonal direction is 119.80°. The camera optical lens 30 satisfies design requirements for large aperture, wide angle and ultra-thinness. The on-axis and off-axis chromatic aberrations are fully corrected, thereby achieving excellent optical performances.
