Specially optimized for 1064nm near-infrared pulsed and ultrafast lasers, it serves as the core optical scanning unit for semiconductor micro-processing, precision laser cutting, micro-hole drilling, laser annealing, 3C ultra-fine marking and new energy electrode processing. Adopting the new-generation iDRIVE full-digital drive architecture and 20-bit high-resolution encoder, it eliminates thermal drift, poor repeatability and dynamic distortion defects of traditional analog galvanometers.

Equipped with a 14mm standard clear aperture, the system supports long-term full-load operation of high-power 1064nm nanosecond, picosecond and femtosecond lasers. With an independent water-cooling circuit and full-digital closed-loop control, it achieves ultra-low thermal drift and excellent long-term batch processing consistency. The native SL2-100 high-speed digital interface ensures low-latency and anti-interference signal transmission, compatible with mainstream high-end laser control systems. It is widely recognized as the preferred scanning solution for high-precision industrial laser mass production equipment.

2. Technical Features

2.1 1064nm Wavelength Specialized Optical Optimization

The optical lenses and coatings are professionally optimized for 1064nm near-infrared lasers, featuring low optical loss and high laser-induced damage threshold. The 14mm large clear aperture ensures high-quality beam transmission with controllable distortion, fully compatible with nanosecond, picosecond and femtosecond ultrafast laser processing, and adaptable to high-energy-density precision manufacturing scenarios.

2.2 Full-Digital Closed-Loop Control with 20-Bit Ultra-High Resolution

Equipped with SCANLAB self-developed iDRIVE full-digital drive technology and high-precision digital encoders, it adopts pure digital closed-loop control without analog noise and drift. The 20-bit ultra-high angular resolution eliminates low-speed jitter and high-speed offset, meeting micro-nano level precision positioning requirements.

2.3 Water-Cooled Constant Temperature Design for Ultra-Low Thermal Drift

The independent water-cooling heat dissipation structure efficiently removes cumulative heat generated during long-term high-load operation, restraining thermal deformation of lenses and mechanical components. After standard preheating, it maintains extremely low gain and zero-offset drift, ensuring consistent dimension, position and morphology of mass-produced workpieces for 8-hour continuous operation.

2.4 Ultra-Fast Dynamic Response Balancing Speed and Precision

Optimized mechanical resonance structure and drive algorithm deliver excellent dynamic follow-up performance. The full-scale 1‰ settling time is only 0.45ms with minimal overshoot. With a standard f=160mm F-theta lens, it achieves a high-quality writing speed of 5.0m/s, supporting high-density dot marking, high-speed vector cutting and high-frequency micro-hole drilling with smooth trajectory and sharp edge performance.

2.5 Industrial Reinforced Structure for Long-Term High-Load Operation

The reinforced industrial housing and precision assembly ensure excellent vibration resistance, impact resistance and environmental adaptability. The sealed water-cooling circuit provides uniform heat dissipation, supporting 7×24-hour uninterrupted full-load operation with low performance attenuation and long service life, reducing equipment downtime and maintenance costs.

2.6 High-Speed Digital Interface with Strong Anti-Interference Ability

The standard SL2-100 high-speed digital interface features low transmission delay and strong electromagnetic interference resistance, avoiding scanning abnormalities caused by analog signal crosstalk and voltage fluctuation. Real-time temperature monitoring, status feedback and fault self-diagnosis enable convenient system integration and intelligent operation maintenance.

2.7 Factory Precision Calibration with Low Distortion

Factory multi-dimensional optical, mechanical and algorithm calibration, combined with original nonlinear and temperature compensation algorithms, ensures ultra-low system nonlinear error and uniform full-field scanning precision. No frequent manual correction is required, maintaining long-term stable accuracy for high-consistency mass production.

4. Operating Principle

After power-on and self-calibration, the SCANLAB INTELLISCAN DE14-1064NM completes system initialization, parameter loading and loop calibration. It receives XY scanning trajectory commands from the upper laser control system via the SL2-100 digital interface. The iDRIVE digital drive chip analyzes and calculates the commands to precisely drive the X/Y galvanometer motors and deflect the optical mirrors, realizing accurate focused laser scanning on the working plane with the matched F-theta lens.

During operation, the 20-bit high-precision encoder real-timely collects and feeds back the shaft angle position signal to form closed-loop negative feedback, correcting deflection errors and dynamically compensating temperature drift and mechanical resonance deviation. The continuous water-cooling system eliminates accumulated operating heat and restrains thermal deformation-induced zero offset and gain drift, ensuring trajectory consistency and dimensional stability during long-term batch processing.

The system real-timely monitors power supply, temperature, loop status and communication link, actively alarming and limiting abnormal actions under faulty conditions, ensuring safe and stable operation for high-precision laser processing.
