In an exemplary embodiment, at least one of the mirror surfaces of each lens is an aspheric mirror surface, i.e., at least one of the object side surface of the first lens to the image side surface of the eighth lens is an aspheric mirror surface. The aspheric lens is characterized in that: the curvature varies continuously from the center of the lens to the periphery of the lens. Unlike a spherical lens having a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has better curvature radius characteristics, and has advantages of improving distortion aberration and improving astigmatic aberration. After the aspheric lens is adopted, the aberration generated during imaging can be eliminated as much as possible, thereby improving the imaging quality. Optionally, at least one of an object-side surface and an image-side surface of each of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens, and the eighth lens is an aspherical mirror surface.

The present application also provides an imaging device whose electron photosensitive element may be a photo-coupled device (CCD) or a complementary metal oxide semiconductor device (CMOS). The imaging device may be a stand-alone imaging device such as a digital camera, or may be an imaging module integrated on a mobile electronic device such as a mobile phone. The imaging device is equipped with the optical imaging lens described above.
Exemplary embodiments of the present application also provide an electronic apparatus including the above-described imaging device.
However, it will be appreciated by those skilled in the art that the number of lenses constituting an optical imaging lens may be varied to achieve the various results and advantages described in the present specification without departing from the claimed subject matter. For example, although eight lenses are exemplified in the embodiment, the optical imaging lens is not limited to include eight lenses.
