Problems solved by technology

[0003] However, due to the increasing number of applications for mobile phones, people can no longer live without mobile phones, so the appearance of mobile phones also requires larger and larger mobile phone screens. Traditionally, the screen will dig holes to allow the lens to sink under the screen. This will cause the screen to be unable to display the part where the hole is dug, which will cause aesthetic discomfort in perception, and will also complicate the process assembly, resulting in loss of yield rate and increased cost

Embodiment 1

[0051] This example provides reference image 3 As shown in the figure, a lens with an aperture far away from the lens is provided, wherein the lens is composed of two plastic lenses, and the "+, -" lens group structure starts from the object side: aperture aperture (STO), lens (P1) and lens ( P2).

[0052] The lens (P1) of this embodiment is a positive lens, and its surface close to the object side is called P1R1, and its center is convex toward the object side; its surface close to the image side is called P1R2, and its center is convex toward the image side.

[0053] The lens (P2) of this embodiment is a negative lens, and its side close to the object side is called P2R1, and its center is convex toward the object side; its side close to the image side is called P2R2, and its center is convex toward the image side, and its center is convex toward the object side. The edge is gradually convex toward the image side.

[0054] In this embodiment, the lens further includes an ...

Embodiment 2

[0058] At a specific implementation level, this embodiment provides a lens with an aperture far away from the lens, refer to Figure 4-7 As shown in the figure, the lens is composed of two plastic lenses, the "+, -" lens group structure, the order starts from the object side: aperture aperture (STO), lens (P1) and lens (P2).

[0059] The lens (P1) of this embodiment is a positive lens, and its surface close to the object side is called P1R1, and its center is convex toward the object side; its surface close to the image side is called P1R2, and its center is convex toward the image side.

[0060] The lens (P2) of this embodiment is a negative lens, and its side close to the object side is called P2R1, and its center is convex toward the object side; its side close to the image side is called P2R2, and its center is convex toward the image side, and its center is convex toward the object side. The edge is gradually convex toward the image side.

[0061]In this embodiment, the ...

Embodiment 3

[0068] At a specific implementation level, this embodiment provides a lens with an aperture far away from the lens, refer to Figure 8-11 As shown in the figure, the lens is composed of two plastic lenses. The "+, -" lens group structure starts from the object side: aperture aperture (STO), lens (P1) and lens (P2).

[0069] The lens (P1) of this embodiment is a positive lens, and its surface close to the object side is called P1R1, and its center is convex to the object side; its surface close to the image side is called P1R2, and its center is convex to the image side.

[0070] The lens (P2) of this embodiment is a negative lens, and its side close to the object side is called P2R1, and its center is convex toward the object side; its side close to the image side is called P2R2, and its center is convex toward the image side, and its center is convex toward the object side. The edge is gradually convex toward the image side.

[0071] In this embodiment, the lens further incl...

Abstract

The invention relates to the technical field of lens accessories, in particular to a lens with an aperture away from a lens, comprising a positive lens, the center of which close to an object side surface is convex towards the object side, and the center of which close to an image side surface is convex towards the image side; the center, close to the object side surface, of the negative lens is convex towards the object side, and the center, close to the image side surface, of the negative lens is convex towards the image side; and the aperture diaphragm is used for controlling the light quantity of light entering the light-sensitive surface in the body through the lens. According to the design that the aperture is far away from the lens, compared with the design that the aperture is on the lens, the opening in the screen is much smaller than the opening in the screen of a traditional lens. Therefore, a small screen opening can be obtained, and the attractiveness is improved.

Description

technical field [0001] The invention relates to the technical field of lens accessories, in particular to a lens with an aperture away from a lens. Background technique [0002] In the current era of advanced information, the proportion of dependence on electronic products is increasing, which makes human beings more inseparable from the convenience brought by electronic products. Therefore, the product of mobile phones is extended. In the past, mobile phones were only used to receive messages and answer calls. The invention of the LCD screen and the development of network information have made the application in the 3C industry chain more and more demanding for the application of optical lenses. From the initial VGA models to 2M~5M~8M~13M, the demand for pixels is increasing Therefore, mobile phones have gradually replaced the application of digital cameras and become a necessity for taking pictures in everyone's life. [0003] However, due to the increasing number of appl...
