Abstract
An optical imaging system is provided. The optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens, and a tenth lens, sequentially disposed from an object side to an imaging side. The first lens may have positive refractive power, the second lens may have positive refractive power, and two of the third to fifth lenses may have positive refractive power.
