Optical Actuators: The Overlooked Risk Node
Executive Summary As global tech competition intensifies and rare earth elements become increasingly strategic, a quiet yet critical vulnerability is emerging within the imaging module supply chain: optical actuators. Although these components account for only 15–20% of camera module costs, they are essential to core functions such as autofocus and image stabilization, with applications ranging from smartphones and AR headsets to autonomous vehicles and medical systems. Their deep dependence on Chinese-sourced rare earth magnets, particularly
