发明名称 OPTICAL IMAGE CAPTURING ASSEMBLY
摘要 An optical image capturing assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element and a fourth lens element. The first lens element with positive refractive power has a convex object-side surface. The second lens element with negative refractive power has a concave object-side surface and a convex image-side surface. The third lens element with positive refractive power is made of plastic material, and has a convex object-side surface and a convex image-side surface. The fourth lens element with negative refractive power is made of plastic material, and has a convex object-side surface and a concave image-side surface. The object-side surfaces and the image-side surfaces of the third lens element and the fourth lens element are aspheric. The fourth lens element has at least one inflection point formed on at least one surface thereof.
