Metalenses gain durability, adaptive optics, and self-cleaning capability

Researchers developed a new encapsulation approach for metalenses. Metalenses, composed of subwavelength nanostructures that manipulate light, are celebrated for their potential to replace bulky optical components. Their unique functionalities—ranging from improved imaging resolution to advanced beam shaping—have spurred interest in applications from augmented reality to LiDAR systems. However, their fragility under mechanical stress and environmental exposure remains a barrier to commercialization.
