Abstract
An optical imaging lens set includes a first lens element with an object-side surface of a convex part in a vicinity of the optical axis, a second lens element with an image-side surface of a concave part in a vicinity of its periphery, the first lens element being glued to the second lens element to eliminate an air gap, a third lens element with an object-side surface of a concave part in a vicinity of its periphery, a fourth lens element and a fifth lens element of plastic material, ALT being the total thickness of the five lens elements and Gmax being the max value of the air gap from the first lens element to the fifth lens element so that ALT/Gmax≤2.2.
Claims20
An optical imaging lens set, from an object side toward an image side in order along an optical axis comprising:
- a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element, the first lens element to the fifth lens element each having an object-side surface facing toward the object side as well as an image-side surface facing toward the image side, wherein:
- the first lens element has positive refractive power and the first lens element is glued to the second lens element without an air gap;
- the third lens element has negative refractive power and the object-side surface of the third lens element has a concave portion in a vicinity of a periphery of the third lens element;
- and
- the fifth lens element has positive refractive power;
- wherein, lens elements having refractive power included by the optical imaging lens set are only five lens elements described above.
