Abstract
An optical lens for use in a camera module comprises a first lens and a second lens that are sequentially arranged from an object side to an image side. An object side surface of the first lens and an object side surface of the second lens are convex surfaces. The first lens has an Abbe number vd1, with 60≤vd1≤90. The first lens has a refractive index nd1, the second lens has a refractive index nd2, with 1.65≤nd2≤2, and 0.2≤nd2−nd1≤0.5. The second lens has an Abbe number vd2, with 40<vd1−vd2. The optical lens has a total track length TTL and a half-image height IH, with 0.45≤TTL/(2*IH)≤0.6.
