anti-halation photoelectric glass is a special key material used in low-light night vision devices. It has high transmittance for ultraviolet, visible, and near-infrared light within the effective range, while forming a highly efficient absorbing layer with a non-reflective interface around it. The highly efficient absorbing layer is formed by special processing on the surface of the glass substrate, providing strong absorption characteristics for stray light. As a result, it can eliminate halation and improve image clarity.
