圖14A是圖13的成像鏡頭的一實施例的像散與場曲圖，圖14B是圖13的成像鏡頭的一實施例的畸變圖，而圖14C是圖13的成像鏡頭的一實施例的調製傳遞函數圖。如圖14A至圖14C所示，本實施例的成像鏡頭100f適於消除因光束入射角過大而造成的像差，以提供良好的成像品質。14A is an astigmatism and field curvature diagram of an embodiment of the imaging lens of FIG. 13, FIG. 14B is a distortion diagram of an embodiment of the imaging lens of FIG. 13, and FIG. 14C is an embodiment of the imaging lens of FIG. Modulation transfer function diagram. As shown in FIGS. 14A to 14C, the imaging lens 100f of the present embodiment is adapted to eliminate aberrations caused by excessive incident angle of the light beam to provide good imaging quality.

除了上述實施例所列舉的其他透鏡的配置之外，在其他實施例中，第十二透鏡也可以配置於第二透鏡G2與第三透鏡G3之間，以減緩光束通過第二透鏡G2擴散的作用，此成像鏡頭可具有良好的成像品質。此外，於其他實施例中，成像鏡頭也可以在第二透鏡G2的二側各增設一片具有正屈光度的透鏡。In addition to the configuration of other lenses listed in the above embodiments, in other embodiments, the twelfth lens may also be disposed between the second lens G2 and the third lens G3 to slow the diffusion of the light beam through the second lens G2. In effect, this imaging lens can have good imaging quality. In addition, in other embodiments, the imaging lens may also add a lens with positive refracting power on each side of the second lens G2.

在本發明實施例的成像鏡頭包括十一片透鏡，由於在放大側至縮小側排列的這些透鏡皆具有屈光度，並且依據排序分別具有正、負、負、正、正、負、正、正、正、負、正屈光度，所以此成像鏡頭可以提供良好的成像品質。此外，本發明實施例的成像鏡頭因更可包括一片或多片的其他透鏡，也有助於提供良好的成像品質。The imaging lens of the embodiment of the present invention includes eleven lenses, and since the lenses arranged on the magnification side to the reduction side all have diopter, and have positive, negative, negative, positive, positive, negative, positive, positive, respectively according to the ordering. Positive, negative, positive diopter, so this imaging lens can provide good imaging quality. In addition, the imaging lens of the embodiment of the present invention also contributes to providing good image quality because it can include one or more other lenses.

雖然本發明已以實施例揭露如上，然其並非用以限定本發明，任何熟習此技藝者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention. The scope is subject to the definition of the scope of the patent application attached.
