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 parallel plate 4 from the object side to the image side. The line O represents the optical axis of lens 10, and Z OBJ On behalf of the property, Z IMG On behalf of the image side, the first lens 1 at the object side of the lens when in use is the lens that light contacts first. The digital camera lens also includes an aperture 6 located at the object side and placed in front of the first lens 1, and an image sensing element 5 located at the image side and behind the parallel plate. The image sensing element 5 includes a Imagine surface 52.

[0020] The first lens 1 is a double-sided spherical positive lens convex to the object side, including a first spherical surface 12 and a second spherical surface 13, wherein the first spherical surface 12 is convex to the object side, and the second spherical surface 13 is a spherical surface with a larger c...

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 present 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 technology, portable electronic devices, such as mobile phones, are becoming more and more widely used. At the same time, they are becoming more lightweight, beautiful and multifunctional. 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 popular among users because they can realize instant shooting functions and are convenient 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 hope to have higher imaging quality fo...
