Embodiment Construction

[0019] see figure 1 The digital camera lens 10 of the present invention includes a first lens 1 , a second lens 2 , a third lens 3 and a glass plate 4 sequentially from the object side to the image side. Where line O represents the optical axis of lens 10, Z OBJ represents the object space, Z IMG Representing the image side, the first lens 1 at the object side of the lens during use is the lens that light first contacts. The digital camera lens also includes a diaphragm 6 placed in front of the first lens 1 on the object side and an image sensor 5 placed behind the glass plate on the image side. The image sensor 5 includes a Imaging surface 52 .

[0020] The first lens 1 is a double-sided spherical positive lens that is convex toward the object side, and includes a first spherical surface 12 and a second spherical surface 13, wherein the first spherical surface 12 is convex toward the object side, and the second spherical surface 13 is a spherical surface with a relatively ...

Abstract

This invention camera lens includes a first lens, which is a double-sided spherical positive lens convex to the object including a first sphere and a second sphere made of glass materials, a second lens, which is a concave-convex double-sided non-spherical negative lens including a third non-sphere and a fourth sphere made of plastics and a third lens-a double sided non-spherical positive lens convex to the image including a fifth non-sphere and a sixth non-sphere made of plastics.

Description

【Technical field】 [0001] The invention relates to a digital camera lens, in particular to a digital camera lens that can be used in conjunction with a portable electronic device. 【Background technique】 [0002] With the continuous development of science and technology, portable electronic devices, such as mobile phones, are widely used and tend to be lightweight, beautiful and multi-functional. Among them, the camera function is an additional function of the newly developed portable electronic devices in recent years. Mobile phones with digital cameras are more and more favored by users because they can realize the instant shooting function and are easy to use. Due to the small size of the mobile phone, the digital camera lens module that needs to be installed in the mobile phone has a small size. While people are pursuing the miniaturization of digital camera modules for mobile phones, they also hope to have higher imaging quality for the objects they shoot, and the imagin...
