The Characteristics of JS1550 System:

1. The scanner hand piece designing was adopted the unique vertically into the light structure, only weights 290g, the operation is flexible and convenient;
2. Specially self-developed F-theta lens for 1550nm laser source, the laser beam input directly without beam expander, the uniformity of scanning point is very fine in the marking plane, the minimum beam diameter can reach 0.1mm;
3. Adopted the world's smallest scanning motors, the photoelectric sensors is imported from America, only weighs 13g, the marking speed is two times faster than common scanners, the setting time reaches 0.35ms.
4. The Driving system adopted the control method of Germany galvo scanners, two motors are centralized controlled by only one drive board, the performance is stable, reliable and high accuracy. All precision electronic components are imported from abroad.
5. The control board are designed according to the industrial computer motherboard standard, comprehensive configuration isolation measures, with good electromagnetic compatibility, stronger anti-interference ability, can effectively prevent the motherboard damage caused by external input error signals or power supply;
6. With powerful software function, convenient parameter settings, a variety of scanning shapes and scanning mode for options, the scanning shapes can be two-way adjusted;
7. This model has the self-inspection and protection signal output function. It will output the protection signal within 0.1ms when the scanner working abnormal, to shut down the laser power supply thereby effectively to prevent medical accidents.
