Embodiment Construction

[0023] The present invention will be described below in conjunction with specific embodiments.

[0024] Such as Figure 1 to Figure 5 Shown, a kind of photographic lens, it comprises diaphragm 6, lens lens one 1, lens lens two 2, lens lens three 3, lens lens four 4 and glass filter plate 5 arranged in order from object side to imaging side 7, It adopts the front stop 6, and the stop 6 is located at the side end of the surface sequence 10 of the lens lens 1; the lens lens 1, the lens lens 2, the lens lens 3 3 and the lens lens 4 4 are all aspherical plastics Lens, both sides of the lens are even aspheric. When the above-mentioned lens system is in operation, the incident light from the object side passes through the first lens 1 , the second lens 2 , the third lens 3 , the fourth lens 4 and the glass filter 5 to form an image at the imaging plane.

[0025] Such as figure 1 shown and figure 2 As shown, in this embodiment, both sides of the lens lens 1 are convex; the lens l...

Abstract

The invention relates to the technical field of an optical device, and especially relates to a photographic lens. By utilizing a structure of a front-placed aperture stop and four aspheric surface plastic lenses, and through a special aspheric surface combination design, the photographic lens has the advantages of small pixel unit, small module size, short total lens length, 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 aspheric photographic lens used in an 8-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 high-pixel lenses with small modules. [0003] Every year, the mobile phone market is undergoing tremendous changes, and the emerging new technologies are constantly improving consumers' vision and taste. The diversification of mobile phone styles, the decline in prices, and the continuous enrichment of t...
