    摘要: An imaging lens assembly comprises a fixing diaphragm (70) and an optical set including four lenses. An arranging order from an object side to an image side is: a first positive lens (10); a second negative lens (20); a third positive lens (30); and a fourth negative lens (40). At least one surface of the first and the second lenses (10),(20) is aspheric. At least one surface of the third and the fourth lenses (30),(40) are aspheric; the aspheric surface of the fourth lens has at least one inflection point. The fixing diaphragm (70) is disposed between an object and the second lens (20). By the concatenation between the lenses and the adapted curvature radius, thickness, interval, refractivity, and Abbe numbers, the assembly attains a big diaphragm with wide-angle, a shorter height, and a better optical aberration.

    摘要: A wide-angle imaging lens assembly comprises a fixing diaphragm (10) and an optical set including two lenses. An arranging order from an object side to an image side is: a first lens (20) with a positive refractive power defined near an optical axis, a convex surface directed toward the object side, and a convex surface directed toward the image side; and a second lens (30) with a positive refractive power defined near the optical axis, a concave surface directed toward the object side, and a convex surface directed toward the image side. At least one surface of the two lenses (20) (30) is aspheric. The fixingdiaphragm (10) is disposedbetween an object and the second lens (30). By the concatenation between the lenses and the adapted curvature radius, thickness/interval, refractivity, and Abbe numbers, the assembly attains a big diaphragm with ultra-wide-angle, a shorter height, and a better optical aberration.
