Dynamic Focusing Module

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, as well as laser ablation applications.
