Optical imaging system including eight lenses of ++−+−+−− or ++−+−++− refractive powers

An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens, which are sequentially arranged from an object side optical imaging system. The first lens has positive refractive power and the second lens ha...

More Information
Summary:An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and an eighth lens, which are sequentially arranged from an object side optical imaging system. The first lens has positive refractive power and the second lens has positive refractive power. At least one of the lenses has negative refractive power with a refractive index greater than 1.68.
