The ever-increasing demand for smaller sized mobile devices, such as cell phones, digital cameras, etc. has triggered a corresponding and growing need for smaller sized photography modules. Such modules may comprise elements such as an optical imaging lens, a module housing unit, and an image sensor, etc., contained therein. Size reductions may be contributed from various aspects of the mobile devices, which includes not only the charge coupled device (CCD) and the complementary metal-oxide semiconductor (CMOS), but also the optical imaging lens mounted therein. When reducing the size of the optical imaging lens, however, achieving good optical characteristics may present a challenging problem.
Therefore, there is a need to develop optical imaging lens which may be capable to be placed with six lens elements therein, may have a shorter length, while also maintaining good optical characteristics.
