Z-axis Galvo Scan Head

High-precision grating encoder as feedback with 25 bit position resolution. Extremely low noises, excellent linearity and lowest drift. FPGA-based digital processing driver technology with excellent anti-interference ability and dynamic performance. Adopting a fully digital motor and driving scheme, the positioning accuracy is high and the drift is small. According to the lasers of different wavelengths and spot diameters, Z-axis lenses with different clear apertures can be flexibly configured. Mainly applying to dynamic auto-focusing, it is able to combine with scanner system to 3D scanning solutions. The widely applications are used successfully in 3D laser marking, 3D printing and large format processing, etc.
