Following table 13 lists the numerical value that each conditional is corresponded in present embodiment according to above-mentioned condition formula.Obviously, this realityThe 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 1.982mm, and full filed image height is3.512mm, the field angle of diagonal are 83.07 °, wide-angle, ultra-thin, and on axis, the outer chromatic aberation of axis fully makes corrections, and haveOutstanding 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 inventionFormula, and in practical applications, can to it, various changes can be made in the form and details, without departing from the spirit and model of the present inventionIt encloses.
