Lens Assembly
A lens assembly includes a first, second, third, stop, fourth, fifth, sixth, and seventh in order from an object side to an image side along an optical axis. The first lens is a meniscus lens with refractive power and includes a convex surface facing the object side and a concave surface facing the...

| Zusammenfassung: | A lens assembly includes a first, second, third, stop, fourth, fifth, sixth, and seventh in order from an object side to an image side along an optical axis. The first lens is a meniscus lens with refractive power and includes a convex surface facing the object side and a concave surface facing the image side. The second lens is with negative refractive power. The third lens is with positive refractive power and includes a convex surface facing the image side. The fourth lens is with refractive power and includes a convex surface facing the image side. The fifth lens is with positive refractive power and includes a convex surface facing the object side. The sixth lens is a biconcave lens with negative refractive power. The seventh lens is with refractive power and includes a convex surface facing the image side. The lens assembly satisfies: 4.3≤TTL/BFL≤5.3. |
