Full-sea-depth ultra-high-definition electric zoom lens with variable aperture

Abstract

The invention relates to a lens, in particular to a full-sea-depth ultra-high-definition electric zoom lens with a variable aperture. The problems that when a fixed-focal-length fixed-aperture lens isused in deep sea field detection at present, the detection efficiency is low, high-quality images cannot be obtained, and a traditional variable-aperture zoom lens is instable in imaging, easy to block and incapable of meeting the detection requirements in the deep sea field due to the large size and contradiction between the traditional zoom lens and the miniaturization design of a compression-resistant closed cabin are solved. The lens is characterized in that the zoom lens comprises a main lens barrel, a first front group coaxially mounted in front of the main lens barrel, a focusing cam sleeving the outer circle of the first front group, a zoom cam sleeving the outer circle of the main lens barrel, and a second front group, a zoom group, a compensation group, a variable aperture assembly, a middle fixed group, an aberration stabilization group and a rear fixed group which are coaxially arranged in the main lens barrel in sequence from front to back, the zoom lens further comprisesa focusing drive group and a zoom drive 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 linearly slide along the axial direction 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 ...

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
