Abstract
An optical imaging system includes a first lens having a positive refractive power and a concave object-side surface, a second lens having a positive refractive power, a third lens having a negative refractive power, a fourth lens having a positive refractive power, and a fifth lens having a positive refractive power and a concave image-side surface. The first through fifth lenses are sequentially disposed in ascending numerical order from an object side of the optical imaging system toward an imaging plane of the optical imaging system.
