Abstract
An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens sequentially arranged on an optical axis from an object side to an image side, wherein an image-side surface of the first lens and an image-side surface of the sixth lens may be concave, and 0.7<TL/f<1.0 and |Nd2-Nd3|<0.2 in which TL may be a distance from an object-side surface of the first lens to an imaging plane, f may be an overall focal length of the optical imaging system, Nd2 may be a refractive index of the second lens, and Nd3 may be a refractive index of the third lens.
