More Information
Summary:An optical imaging system includes a first lens having an object-side surface that is convex; a second lens having a refractive power; a third lens having a refractive power; a fourth lens having a refractive power; a fifth lens having a refractive power and an object-side surface that is concave; and a sixth lens having a refractive power and an object-side surface that is concave, wherein the first lens through the sixth lens are sequentially disposed in numerical order from an object side of the optical imaging system toward an imaging plane, and the optical imaging system satisfies the conditional expressions 0.7 < TL/f < 1.0 and TL/2 < f1, where TL is a distance from the object-side surface of the first lens to the imaging plane, f is an overall focal length of the optical imaging system, and f1 is a focal length of the first lens.
