Underwater white glimmer detection lens, mechanical packaging structure and underwater camera instrument

By designing a white low-light large field-of-view detection lens suitable for underwater applications, the problems of insufficient light transmission and poor stability of underwater lenses under low illumination conditions have been solved. This enables the switching between large-area detection and small-area identification imaging, resulting in clear imaging, a large field of view, and excellent aberration correction, making it suitable for underwater detection and photography.

AI Technical Summary

Technical Problem

Existing underwater lenses have insufficient light transmission under low light conditions, resulting in poor image quality. They cannot simultaneously handle large-scale monitoring and small-scale identification, and their stability in underwater environments is poor, with inadequate aberration correction.

Method used

An underwater white low-light wide-field detection lens was designed. It adopts a single-lens imaging method and features ultra-wide-angle, zoom, and large-aperture capabilities. The lens material and structural design are adapted to the underwater environment. The lens shell is made of 6063 aluminum alloy, and the lenses are fixed securely. The inside of the lens barrel is coated with an anti-light material. The lens material and structure have been optimized to improve image quality.

Benefits of technology

It enables imaging switching between large-scale detection and small-scale identification in low-light underwater environments, with clear imaging, a field of view of up to 120°, stable lenses, and excellent aberration correction, making it suitable for underwater detection and photography.

Abstract

The invention discloses an underwater white glimmer detection lens, a mechanical packaging structure and an underwater camera. The lens sequentially comprises a first lens to a twelfth lens from an object space to an image plane. The lens adopts a zoom structure, so that the switching of imaging functions of large-range detection and small-range accurate recognition can be realized. A full-glass lens structure is adopted, the large aperture and the ultra-wide angle are achieved, and large-range and high-brightness clear imaging can be achieved in an underwater low-illumination environment. Through accurate design and arrangement of curvature radius, thickness and material of each lens, various aberrations, especially distortion and chromatic aberration, are effectively corrected. The lens is compact in overall structure, each lens is stably matched with the lens barrel and the space ring, and the lens has high environmental adaptability and is suitable for the fields of underwater detection, underwater photography and the like.
