Abstract
The disclosure discloses an optical imaging system. The optical imaging system includes, sequentially from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. The first lens has a focal power, and an object side surface thereof is a convex surface; the second lens has a focal power; the third lens has a focal power, and an image side surface thereof is a convex surface; the fourth lens has a focal power, an object side surface thereof is a convex surface, and an image side surface thereof is a concave surface; the fifth lens has a positive focal power, and an object side surface thereof is a convex surface; and the sixth lens has a negative focal power, and an object side surface thereof is a concave face.
