The application belongs to the technical field of nano coating, and particularly relates to a super-black nano coating structure, which comprises a substrate, a transition layer deposited on the surface of the substrate by ALD, a light-absorbing layer deposited on the surface of the transition layer by ALD, and an anti-corrosion layer deposited on the surface of the light-absorbing layer by ALD. Compared with the prior art, the application uses the ALD technology to realize the super-black film of the substrate / transition layer (increasing adhesion) / light-absorbing layer (multi-layer interference film layer) / anti-corrosion layer (single layer or multiple layers) with low temperature (50-250 DEG C), high coverage, ultra-low reflection (less than or equal to 0.5%), high absorption efficiency (greater than or equal to 99.00%) and good bonding force, effectively expands the selection range of the substrate material, solves the problem that the current super-black film manufacturing process has a great limitation on the substrate material, and is difficult to be compatible with the low-temperature control and high coverage, high absorption rate of the film.

The utility model discloses a lens cone seat insert core segmentation position setting structure, which comprises a lens cone seat, the top of the lens cone seat is fixedly connected with a top surface, the lens cone seat is arranged by adopting an integrated female die, and the inner wall of the lens cone seat is arranged to be a continuous smooth curved surface. The problems of abnormal reflection and poor glare possibly caused by the traditional insert core segmentation design are effectively avoided, the integrated female die design ensures the continuous smooth curved surface of the inner wall of the lens barrel base, reflection and scattering of light rays during passing are reduced, and therefore the imaging quality and performance stability of the lens are improved. The super black plating layer arranged on the top surface further enhances the light absorption capability of the lens, reduces unnecessary reflected light rays, effectively reduces the occurrence of a dazzle light phenomenon, and meanwhile, the top surface is in smooth transition connection with the lens barrel seat through the arc part, so that the design is attractive, light ray reflection and scattering at the joint are reduced, and the service life of the lens is prolonged. And the imaging effect of the lens is further improved.

The invention discloses a high-temperature-resistant stray light-eliminating inorganic super-black coating and a preparation method thereof, and belongs to the technical field of functional coatings and preparation thereof. The problem that an existing ultra-black coating cannot resist the extreme high temperature of 800 DEG C and cannot meet the coating requirements of precision parts at the same time is solved.
