Figure 10, Figure 11 respectively illustrate shooting of light of the wavelength for 486nm, 588nm and 656nm Jing Guo the 3rd embodiment
Axial aberration and ratio chromatism, schematic diagram after optical lens 30.Figure 12 then shows that the light that wavelength is 588nm passes through the 3rd
The curvature of field and distortion schematic diagram after the camera optical camera lens 30 of embodiment.
Table 13 below lists the numerical value that each conditional is corresponded in present embodiment according to above-mentioned condition formula.Obviously, this reality
The imaging optical system for applying mode meets above-mentioned conditional.
In the present embodiment, the Entry pupil diameters of the camera optical camera lens are 2.141mm, and full filed image height is
3.928mm, the angle of visual field of diagonal are 79.13 °, wide-angle, ultra-thin, and on its axle, the outer chromatic aberation of axle fully makes corrections, and have
Outstanding optical signature.
【Table 13】
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific embodiment party of the present invention
Formula, and in actual applications, can to it, various changes can be made in the form and details, without departing from the spirit and model of the present invention
Enclose.
