Problems solved by technology

[0006] However, the above-mentioned patent applications all adopt the traditional method of adjusting the focal length of the lens by using the axial distance of the lens, that is, moving the lens in the front and rear direction (axial direction) to adjust the focus. Installation is inconvenient, and for high-quality lenses, the lens is easily damaged during carrying and transportation; especially in industrial applications, the lens setting position between devices is often small, and the axial focusing method cannot meet the application needs

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] refer to figure 1 , figure 2 As shown, it is an assembly diagram and an exploded view of the left and right movable focusing lens implemented in the present invention. As shown in the figure, the focusing lens includes a basic lens 1 and a radial lens assembly 2, and the radial lens assembly 2 is set on the front of the basic lens 1.

[0028] Specifically, the radial lens assembly 2 includes a fixed assembly and left and right lenses 23, 22, wherein the fixed assembly includes a mobile chassis 21 and a lens moving part, and further, the lens moving part includes a left lens moving part 25...

Abstract

The present invention discloses a left and right mobile focusing lens comprising a basic lens and further comprising a radial lens assembly arranged at the front portion of the basic lens. The left and right mobile focusing lens changes the way of setting the lens assembly in the axial direction by the setting of the radial lens assembly, so that the increased lens is moved closer to the center of the lens from the side of the lens and the purpose of focusing is achieved, thereby effectively shortening the length of the lens and reducing the lens space occupied.

Description

technical field [0001] The invention belongs to the technical field of photography or photography, and in particular relates to a focusing lens for photography or photography. Background technique [0002] The lens is a necessity for people to take pictures or take photos. People obtain the pictures or videos taken through the lens, so the lens becomes a very important part of the camera or photography. However, in photography or photography, people do not stand fixedly in one position to shoot, and often need to change positions. At this time, a simple fixed lens cannot meet the needs, and needs to be adjusted. Focusing or focusing, focusing refers to changing the image distance v, that is, changing the distance between the optical center of the lens and the film plane to obtain a clear image of the object. [0003] At present, except for some low-end point-and-shoot lenses that have no focusing mechanism and cannot change the image distance, all lenses, regardless of fi...
