Problems solved by technology

[0005] The purpose of the present invention is to provide a full-sea deep ultra-high-definition motorized variable-aperture zoom lens to solve the problem of using a fixed-focus and fixed-aperture lens in the current deep-sea field. The detection efficiency is low and high-quality images cannot be obtained, while the traditional Due to the large size of the variable aperture and zoom lens, it contradicts the miniaturization design of the pressure-resistant airtight cabin, the imaging is unstable, easy to get stuck, and cannot meet the technical problems of deep-sea field detection requirements

Embodiment Construction

[0060] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0061] see figure 1 and figure 2 , the present invention is a full-sea deep ultra-high-definition motorized iris zoom lens, including a main lens barrel 1, a first front group 2 coaxially installed in front of the main lens barrel 1, and an adjusting lens set on the outer circle of the first front group 2. The focus cam 12, the zoom cam 10 set on the outer circle of the main lens barrel 1, the second front group 3, the variable magnification group 4, the compensation group 5, which are coaxially arranged in the main lens barrel 1 from front to back in sequence The variable aperture assembly 6 , the middle fixed group 7 , the aberration stabilization group 8 and the rear fixed group 9 also include a focus driving group 13 and a zoom driving group 11 .

[0062] see figure 2 and image 3 , the inside of the main lens barrel 1 is fixedly pr...

Abstract

The present invention relates to a lens, in particular to a full-sea deep ultra-high-definition electric variable aperture zoom lens, which solves the problem of using a fixed focal length and fixed aperture lens in the current deep-sea field detection, which has low detection efficiency and cannot obtain high-quality images. Due to the large size of the zoom lens, which contradicts the miniaturization design of the pressure-resistant airtight cabin, the imaging is unstable and easy to get stuck, which cannot meet the needs of deep-sea field detection. The special feature of this lens is that it includes the main lens barrel, the first front group coaxially installed in front of the main lens barrel, the focusing cam set on the outer circle of the first front group, and the zoom lens set on the outer circle of the main lens barrel. The cam, the second front group, the zoom group, the compensation group, the iris group, the middle fixed group, the aberration stabilization group and the rear fixed group are coaxially arranged inside the main lens barrel in sequence from front to back, including focusing The driving group and the zoom driving group; the second front group and the rear fixed group are fixedly connected with the main lens barrel; the zoom group, the compensation group, and the aberration stabilization group can slide linearly along the axis of the main lens barrel.

Description

technical field [0001] The invention relates to a lens, in particular to a full-sea deep ultra-high-definition electric variable aperture zoom lens. Background technique [0002] The zoom lens can provide high-magnification small-field images and low-magnification large-field images at the same time. The iris device can adjust the size of the clear aperture of the lens, so that the lens can clearly image objects in different bright and dark scenes. The motorized zoom lens with variable aperture device and imaging electronics components are installed in the pressure-resistant airtight cabin, and with the help of the deep-sea submersible, free detection and photography of targets in the entire deep-sea field can be realized. [0003] However, the current deep-sea field detection uses a fixed focal length, fixed aperture lens, and is matched with a small-sized detector with low resolution, which has low detection efficiency and cannot obtain high-quality images. The reason is ...
