High-resolution and long-and-variable-focus airborne camera lens with automatic focusing and automatic dimming functions

Abstract

The invention relates to a high-resolution long-focus autofocus and auto-adjustment airborne zoom camera lens, characterized in that: the optical system of the lens is respectively equipped with a front fixed group, Magnification group, compensation group, diaphragm assembly and rear fixed group, the front fixed group is provided with negative crescent lens, biconvex lens, positive crescent lens and positive crescent lens in turn, and the described zoom group is provided with negative crescent lens and composed of A double-concave lens and a double-convex lens are closely connected to each other. The compensation group is provided with a double-concave lens and a positive crescent lens. A double-convex lens and a double-concave lens are tightly bonded together and a positive crescent lens, and the rear part is provided with a negative crescent lens and a double-convex lens in sequence. The camera lens has the advantages of long focal length, large target area, large field of view, high resolution, automatic focus, automatic aperture, etc., and is suitable for the field of airborne photography.

Description

Technical field [0001] The invention relates to a high-resolution long-focus autofocus and auto-dimming airborne zoom camera lens, which is suitable for the field of airborne photography. Background technique [0002] At present, the camera lens suitable for routine monitoring requires large observation range, long observation time, small size, light weight and high definition. It can be used for panoramic observation of large areas and small magnifications as well as large magnification observations of small areas. . The optical structure of the traditional mechanically compensated zoom lens is composed of four components: front fixed group, zoom group, compensation group and rear fixed group. However, there are generally poor image quality, large volume, short focal length, The target surface is small, the working distance is short, and it is not suitable for airborne environment, and is not suitable for routine monitoring. In addition, the existing airborne zoom lens is limi...

AI Technical Summary

Problems solved by technology

The optical structure of the traditional mechanically compensated zoom lens consists of four components: the front fixed group, the zoom group, the compensation group and the rear fixed group, but there are generally poor image quality, large size, short focal length, The target area is small, the action distance is short, and it is not suitable for the airborne environment. It is not suitable for routine monitoring.

In addition, the existing airborne zoom lens is limited by the use environment, has a large shape, poor image quality, short focal length and small target surface, which limits the observation ability
