Yamada Optics unveiled a 350mm fog-penetrating zoom lens at a military optics exhibition, with its integrated nano-EBC (Electron Beam Coating) technology emerging as the biggest highlight. Adopting a dual solution of "optical coating + algorithm optimization," the lens achieves high-definition imaging in harsh environments, having passed rigorous military standard tests and entered practical application.

In terms of technical principles, the nano-EBC coating utilizes an electron beam evaporation deposition process in a vacuum environment. It alternates stacking 20 nanolayers of aluminum oxide and silicon dioxide in specific proportions, with each layer’s thickness error controlled within 0.5nm. This structure significantly reduces infrared light scattering, increasing the lens’s infrared transmittance by 40%. Combined with the third-generation "optics + algorithm" fog-penetrating solution, the lens can dynamically adjust the spacing of lens groups to compensate for light refraction deviations, adapting to extreme scenarios such as -20℃ low temperatures and 90% humidity.

Currently, the lens has been successfully applied in northwest border defense monitoring systems, extending the foggy-day monitoring distance from 800 meters to 1,500 meters. It is also compatible with the optical tracking module of anti-drone radars. A responsible person from Yamada Optics’ Marketing Department stated that the company will subsequently develop civilian versions based on this coating technology, focusing on marine fog navigation monitoring and forest fire prevention fields.
