IMAGING LENS SYSTEM

An imaging lens system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens disposed in order from an object side. In the imaging lens system, the first lens has positive refractive power and an object-side surface of the first lens is con...

More Information
Summary:An imaging lens system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens disposed in order from an object side. In the imaging lens system, the first lens has positive refractive power and an object-side surface of the first lens is concave. A field of view of the imaging lens system is 100 degrees or more. In the imaging lens system, a distance TTL from the object-side surface of the first lens to an imaging plane and a height ImgH of the imaging plane satisfy TTL/ImgH<1.5.
