Problems solved by technology

[0002] The currently used mobile phone digital lenses generally have such shortcomings: relatively low pixels, large dimensions
The current mainstream camera phones in the market are mainly low-configuration lenses of 2 million and 5 million pixels. The image quality of the captured images is not ideal in terms of overall clarity or uniformity of illumination, so they can only be used as standby screens or Average appreciation, not nearly enough for great prints
[0003] Moreover, the digital lens for camera phone is too large in shape, the outer diameter is generally larger than M8, and the total length of the optical system is larger than 8mm. It is bulky when used on a built-in camera phone, and it is difficult to achieve an ultra-thin effect.

Embodiment Construction

[0022] The present invention is described in detail below in conjunction with accompanying drawing:

[0023] like figure 1 , 2 As shown, the high-quality wide-angle optical lens can be used for a relatively cheap high-pixel CMOS photosensitive film 11 , including a lens barrel 1 , and a mechanical aperture hole is arranged at the front end of the lens barrel to form an aperture 2 . A first lens 3 , a second lens 4 , a third lens 5 , a fourth lens 6 , a fifth lens 7 and a sixth lens 8 are sequentially arranged in the cavity of the lens barrel and behind the mechanical aperture. Spacers 9 are correspondingly provided between the adjacent lenses.

[0024] The first lens 3 is a positive focal length lens, the first surface 31 facing the object plane is an elliptical aspheric surface, and the second surface 32 facing the image plane is a hyperbolic aspheric surface. The two surfaces of the second lens 4 are meniscus-shaped negative focal length lenses, and both surfaces are hype...

Abstract

The invention relates to a high-image-quality wide-angle optical camera lens. The high-image-quality wide-angle optical camera lens comprises a lens cone. A diaphragm is arranged at the front end of the lens cone. In a cavity of the lens cone, a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens are sequentially arranged behind the diaphragm from outside to inside, and space rings are correspondingly arranged between the adjacent lens. The first lens is a forward focal length lens, the first surface towards the object surface is an oval aspheric surface, and the second surface towards the image surface is a hyperbola aspheric surface. Crescent backward focal length lenses are arranged on the two surfaces of the second lens, and both the surfaces are hyperbola aspheric surfaces. The third lens is a forward focal length lens, the first surface towards the object surface is a hyperbola aspheric surface, and the second surface towards the image surface is an oval aspheric surface. Forward focal length lenses are arranged on the two surfaces of the fourth lens, and both the surfaces of the fourth lens are hyperbola aspheric surfaces. The fifth lens is a backward focal length lens, and both the surfaces of the fifth lens are hyperbola aspheric surfaces. The sixth lens is a backward focal length lens, and both the surfaces of the sixth lens are hyperbola aspheric surfaces.

Description

【Technical field】 [0001] The invention relates to an optical lens, in particular to a miniature camera optical lens applied to high-pixel mobile phones and ultra-thin high-quality cameras. The lens consists of six aspherical plastic lenses with an all-plastic lens structure. 【Background technique】 [0002] The currently used digital cameras for mobile phones generally have such shortcomings: relatively low pixels and large dimensions. The current mainstream camera phones in the market are mainly low-configuration lenses of 2 million and 5 million pixels. The image quality of the captured images is not ideal in terms of overall clarity or uniformity of illumination, and can only be used as a standby screen or Generally appreciated, but far from good enough to print great photos. [0003] Moreover, the digital lens for a camera phone is relatively large in shape, the outer diameter is generally larger than M8, and the total length of the optical system is larger than 8mm. It ...
