Optical processing device, optical lens and manufacturing method thereof

Abstract

The invention provides an optical processing device, an optical lens and a manufacturing method thereof. The optical lens comprises a lens cone and an optical lens module. The lens cone comprises a humidity control bearing part and is provided with an accommodating space and a first light passing port communicated with the accommodating space; the humidity control bearing part defines the first light passing port, the optical lens module comprises an outer lens, the outer lens is maintained at the first light passing port of the lens cone, the outer lens covers the humidity control bearing part, and the humidity of the accommodating space is controlled by the humidity control bearing part.

Description

technical field [0001] The invention relates to the field of optics, in particular to an optical processing device, an optical lens and a manufacturing method thereof. Background technique [0002] Thanks to the rapid development of automobile assisted driving systems in recent years, optical lenses are more and more widely used in automobiles. Furthermore, automotive assisted driving also has higher and higher requirements on the pixels and safety performance of the optical lens, especially the optical lens for vehicle applications. Due to the continuous improvement of the imaging quality requirements of the camera device, the image sensor (CMOS) of the camera device is developing towards the direction of high power. What this brings is that the internal heating value of the camera device increases, which makes the problem of lens fogging increasingly prominent, which greatly affects the imaging effect of the lens, and even endangers driving safety, and may even cause huge...

Problems solved by technology

However, the metal lens barrel 10 ′ is used to replace the common plastic lens barrel, so that the production cost of the optical lens 40 ′ is relatively high, and the weight is relatively large, which does not meet the lightweight design requirements of the optical lens 40 ′.

From the analysis of the design of the lens barrel structure, the improvement effect of improving the fogging problem of the optical lens by promoting the air circulation between the accommodating space 100 ′ of the lens barrel 10 ′ and the external space is relatively weak, and at the same time, it will increase the noise. The impact of light on the light processing device, which in turn affects the normal use of the optical lens 40'
