Description
ExtraScan Laser Scan Head: High-Precision, Stability-Driven Beam Steering Solution
The ExtraScan Laser Scan Head is a next-generation galvanometer scanning solution designed to meet the growing demand for precision, speed, and long-term reliability in industrial laser applications. Engineered with a self-developed high-precision 23-bit grating encoder and a fully digital servo motor, this scan head delivers exceptional positioning accuracy and repeatability, making it ideal for high-end manufacturing scenarios.
High-Resolution Feedback with 23-bit Encoder
At the heart of the ExtraScan system lies its 23-bit optical grating encoder, capable of detecting ultra-fine position changes with sub-microradian resolution. This ensures that the laser beam can be steered with exceptional precision, minimizing deviation even in high-speed, multi-axis applications. Whether for intricate micromachining or fine feature processing, this encoder guarantees stable, repeatable performance.
Real-Time Galvanometer Status Monitoring
The system includes an intelligent real-time monitoring module that continuously evaluates the operational status of the galvanometer motor. By providing instant feedback on motor position, thermal condition, and system health, this feature significantly enhances operational safety and reduces downtime due to undetected faults. Operators can rely on consistent output even in complex or continuous-duty production environments.
Fully Digital Servo System for Drift-Free Performance
Unlike analog or hybrid systems, the ExtraScan Scan Head adopts a fully digital control architecture, eliminating the inherent drift and signal degradation found in traditional analog feedback loops. This digital precision leads to improved stability over long operating cycles, reduced recalibration needs, and better integration with modern laser control software.
