In many industries such as coal mining, urban transportation, and construction, the "eyes" of monitoring equipment - glass windows - are exposed to complex and harsh environments such as sandstorms, oil stains, high temperatures, and humidity all year round. To resist physical wear and environmental erosion and maintain high-definition transparency, the environmental adaptability of windows has become a key indicator of equipment capability.

The actual "working environment" of the camera window is far more harsh than imagined, constantly confronting the five major "enemies" of wind, sand, gravel, oil stains, condensation, frost, electrostatic adsorption, and UV radiation.

In the face of such a severe "survival challenge", Dahua Co., Ltd. has developed nano invisible goggles "- high weather resistant and ultra wear-resistant antifouling optical window. With the double blessing of" special materials+precision technology ", it can prevent pollution, wear and aging from the root, and easily cope with complex environments.

The core secret of this window lies in the special film layer on the surface. The membrane layer is composed of a special core-shell structure of "silicon dioxide+metal doped titanium dioxide". By reducing the surface resistance of the membrane layer and cutting off the path of electrostatic adsorption of dust from the source, it achieves long-term cleanliness. This core-shell structure and organic silicate cross-linking weave into a "three-dimensional protective net" - a tree like macromolecular three-dimensional network cross-linking structure.

This net is firmly and steadily adhered, and a single functional layer can achieve multifunctional integration such as anti fouling, wear-resistant, and hydrophobic. And it is also transparent enough. By optimizing the film thickness, the visible light transmittance is maximized, allowing the camera to capture more clearly.

Having good materials alone is not enough, Dahua's combination of "dual wheel rolling coating technology" provides better protection. By precisely controlling the speed difference between the two wheels and the dynamics of solvent evaporation, the material automatically forms micro nano protrusions on the surface of lotus leaves during solidification, greatly reducing the contact area between water droplets and the film layer. Water droplets fall directly and roll away, truly achieving "no rain or condensation" and solving the problem of fogging and frosting blocking the field of view.

This window is no longer a sample in the laboratory, but widely used in various industries to provide protection for camera windows in different scenarios.
