EL-3.1-10.8
EL-3.1-10.8 is an ultra-compact liquid lens designed for high-volume OEM integration, leveraging Optotune’s proven shape-changing lens technology. By applying electrical current, the lens curvature shifts from concave to convex, enabling fast and precise focal tuning within milliseconds.
Powered by reliable voice-coil actuators, the EL-3.1-10.8 delivers robust autofocus performance across a wide focus range. Its exceptionally thin, lightweight design makes it ideal for integration into lens barrels, AR/VR headsets, and other space-constrained optical systems.
