Embodiment Construction

[0024] The present invention will be described below in conjunction with specific embodiments.

[0025] Such as Figure 1 to Figure 6 Shown, a kind of aspherical high-definition front wide-angle lens, it comprises stop 6, lens lens one 1, lens lens two 2, lens lens three 3 and glass filter 4 arranged in order from object side to imaging side 5, its The aperture 6 is used in front, and the aperture 6 is located at the side end of the face sequence one 10 of the lens lens one 1; the lens lens one 1, the lens lens two 2 and the lens lens three 3 are all aspherical plastic lenses, and the two sides of the lens are uniform. is an even-order aspheric surface. When the above-mentioned lens system is working, the light from the object side passes through the first lens 1 , the second lens 2 , the third lens 3 and the glass filter 4 to form an image at the imaging plane.

[0026] Such as figure 1 shown and figure 2 As shown, in this embodiment, the first lens lens 1 is a convex-co...

Abstract

The invention relates to the technical field of optical devices, in particular to an aspheric high-definition front wide-angle lens which is used for a 2-megapixel camera module of a mobile phone. The aspheric high-definition front wide-angle lens is of a structure with a front diaphragm and three aspheric plastic lenses, is in a special aspheric combination design, and accordingly has the advantages of small module size, wide field angles, high product yield, good imaging effect and low cost.

Description

technical field [0001] The invention relates to the technical field of optical devices, in particular to an aspherical high-definition front wide-angle lens for a 2-megapixel camera module of a mobile phone. Background technique [0002] Since the beginning of 2013, from the smartphone processor to the display screen, to the camera, and even to the related accessories of the mobile phone, there has been a rapidly escalating competition. Since the current flagship mobile phones of various brands have similar configurations, finding product differentiation has become a brain-struggling task. In some recent new mobile phone products, we seem to find that manufacturers pay special attention to the front camera of mobile phones. [0003] In the early days of the birth of the front camera, its pixels were only at the level of 100,000 or 300,000, and the quality of the photos produced was really horrible. Especially when taking a selfie at night, it is either blurry or noisy. In ...
