Minimum 10 nm resolution. High-precision Z-axis focus control of the laser processing head.
In the field of laser processing, precise control of the focal position greatly influences processing quality. Particularly in fine processing and high-precision marking, even slight focal variations in the Z-axis can affect processing width and energy density. The V-308 Voice Coil PIFOC is a Z-axis focus drive with a minimum resolution of 10 nm and a maximum travel range of 7 mm. Its direct drive system enables smooth and fast response, supporting precise focus control for laser processing heads and optical systems. Additionally, it can accommodate heavy optical modules with a gravity compensation function of up to 1 kg. 【Application Scenarios】 - Focus control for laser marking devices - Z-axis positioning for laser fine processing equipment - Focus correction for galvanometer scanner optical systems - Laser processing systems for research and development 【Benefits of Implementation】 - Stabilization of processing quality through improved focus control accuracy - Optimization of processing processes due to high-speed response - Stable optical system control through weight compensation function - Enhanced reproducibility in fine processing
