Fig. 1 to Fig. 3 is the cross-sectional view of the setting of the main element of the lens optical system illustrated according to the of the present invention first to the 3rd embodiment.Lens optical system can be " iris recognition lens optical system " according to an embodiment of the invention.
Referring to Fig. 1 to Fig. 3, each according to an embodiment of the invention in lens optical system can comprise the first camera lens I, the second camera lens II, three-lens III and four-barrel IV, and these camera lenses are successively set on object OBJ from the side of object OBJ and are wherein formed between the imageing sensor IMG of image of object OBJ.First camera lens I can have just (+) refractive power, and can be the crescent camera lens protruded towards object OBJ.Second camera lens II can have just (+) refractive power, and can be the crescent camera lens protruded towards imageing sensor IMG.Three-lens III can have just (+) refractive power, and can be the crescent camera lens protruded towards imageing sensor IMG.First camera lens I can be aspheric lens at least one in three-lens III.In other words, at least one in the first camera lens I to incidence surface 1*, 4* or 6* and exit surface 2*, 5* or 7* of at least one in three-lens III can be aspheric.For example, incidence surface 1*, 4* and 6* of the first camera lens I to three-lens III and exit surface 2*, 5* and 7* can be all aspheric.
Four-barrel IV can have negative (-) refractive power or just (+) refractive power.According to Fig. 1 and Fig. 2, four-barrel IV has negative (-) refractive power, and according to Fig. 3, four-barrel IV has just (+) refractive power.In the embodiment of Fig. 1 to Fig. 3, at least one in the incidence surface 8* of four-barrel IV and exit surface 9* can be non-spherical surface.For example, at least one in the incidence surface 8* of four-barrel IV and exit surface 9* can be the non-spherical surface between heart part and edge wherein with at least one point of inflexion.The incidence surface 8* of four-barrel IV can protrude towards object OBJ at heart part place wherein, and is recessed into towards object OBJ around core.The exit surface 9* of four-barrel IV can be recessed into towards imageing sensor IMG in central part office, and protrudes towards imageing sensor IMG around core.
First camera lens I can have relatively strong just (+) refractive power, and the second camera lens II can serve as aberration correction camera lens to four-barrel IV.

As above the lens optical system according to an embodiment of the invention configured can meet the following conditions at least one in expression formula 1 to 3.
2.5 < | tan θ | < 3.5 [conditional expression 1]
Here, " θ " is the visible angle of lens optical system.
Conditional expression 1 shows the condition of the visible angle for determining lens optical system.In conditional expression 1, when " | tan θ | " be less than or equal to 2.5 lower in limited time, although spherical aberration and intelligent image difference (comaaberration) can reduce, visible angle may also can reduce.By contrast, when " | tan θ | " be more than or equal to 3.5 upper in limited time, although visible angle increases, spherical aberration and intelligent image difference may increase.When meeting the condition of expression formula 1, for example while making spherical aberration and intelligent image difference maintain in kilter, the relatively wide visible angle of (for example) about 70 ° or larger can be obtained.
1.0 < f/D4 < 1.5 [conditional expression 2]
Here, " f " is the focal length of whole lens optical system, and " D4 " is the effective radius of the exit surface 9* of four-barrel IV, that is, and the semiaperture in Y-axis.Because four-barrel IV has maximum outside diameter in the middle of four camera lens I-IV, so can say that the external diameter of lens optical system is determined by " D4 ".
