Abstract
An optical system may include a lens assembly that has two or more single-sided wafer level optics (WLO) lenses arranged to propagate light. The optical system can further include an image sensor, wherein the lens assembly is arranged relative to the image sensor to propagate light received at a first surface of the lens assembly, through the two or more single-sided WLO lenses and to the image sensor. In some embodiments, the optical system further includes a camera which includes the lens assembly and the image sensor. In various embodiments, a smart phone, a tablet computer, or another mobile computing device may include such a camera. In some embodiments, the at least two single-sided wafer level optics (WLO) lenses are each separated by a gap G, wherein the gap may be different between each of the single-sided lenses, and the gap G may be zero.
