  • Wide angle six-piece lens
    Patent number: 10120165
    Abstract: A wide angle six-piece lens includes a first lens having a negative refractive power and an image side as a concave surface, a second lens having a positive refractive power and an object side as a convex surface, an aperture, a third lens having a positive refractive power and an image side as a convex surface, a fourth lens having a positive refractive power and an object surface and an image surface as convex surfaces, a fifth lens having a negative refractive power and an object side as a concave surface, and a sixth lens having a positive refractive power and an object side as a convex surface. The overall effective focal length of the wide angle six-piece lens is f, the focal length of the third lens is f3, and an equation 0.29<f/f3<0.36 is satisfied. As such, a wide angle system is formed and aberration is eliminated.
