This 8-head galvo scan head integrates multiple scan heads into a single compact unit, greatly reducing system footprint and maximizing equipment density. Synchronized multi-head operation enhances processing efficiency and maximizes overall printing throughput.
In-house developed grating optical encoder, with position resolution of up to 23bit.
In-house developed digital driver, providing the feedback loop of position and status.
High accuracy, with long-term drift<50urad.
Multiple galvo scan heads are highly integrated into a single unit, significantly reducing system footprint and enabling higher equipment density.
Synchronized multi-head operation significantly improves processing efficiency and overall printing throughput.
