High Speed Linear Voice Coil Actuator For Optical Lens Autofocus Systems

The Linear Voice Coil Actuator VCAB0436-0187-00A is a high-performance actuator engineered specifically for precision optical inspection systems. With its fast response, nanometer-level resolution, and zero-cogging motion output, this model is ideal for applications requiring highly accurate positioning, stable dynamic motion, and excellent repeatability. It is widely used in high-speed imaging, precision autofocus mechanisms, optical module positioning stages, auto-calibration units, and sub-micron compensation platforms.

The VCAB0436-0187-00A adopts a direct-drive architecture, generating linear force through a permanent magnet assembly and coil interaction without mechanical transmission. This frictionless and backlash-free structure enables extremely smooth and linear motion, ensuring consistent and stable movement for micro-step scanning, multi-point measurement, and rapid trajectory adjustments. For high-magnification lenses, industrial cameras, or microscopic imaging systems, the motor maintains focusing accuracy and positional deviation within microns—or even lower.

In dynamic optical scanning processes such as panel inspection, lens curvature measurement, and wafer defect detection, the VCAB0436-0187-00A’s millisecond-level response significantly improves scanning efficiency. The motor maintains exceptional image stability during high-speed movement, reducing blur and vibration while enhancing measurement precision. With closed-loop position or force control, it supports automated focusing, Z-axis height correction, and fine pressure adjustment based on sensor feedback.
