Wide-angle lens assembly

A wide-angle lens assembly comprising:

• a first lens which is a meniscus lens with negative refractive power;
• a second lens which is a meniscus lens with negative refractive power;
• a third lens which is with refractive power;
• a fourth lens which is with refractive power;
• a fifth lens which is with positive refractive power;
• a sixth lens which is with positive refractive power;
• a seventh lens which is with refractive power and comprises a concave surface facing an object side;
• an eighth lens which is with refractive power;
• a ninth lens which is with refractive power;
• and
• a tenth lens which is with refractive power and comprises a concave surface facing an image side;
• wherein the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens, the eighth lens, the ninth lens, and the tenth lens are arranged in order from the object side to the image side along an optical axis;
• wherein the wide-angle lens assembly satisfies:
• 0.7<TTL/θ<0.82;
• wherein TTL is an interval in mm from an object side surface of the first lens to an image plane along the optical axis and θ is a half field of view in degree for the wide-angle lens assembly.
