Release time:2016-01-27 13:40  

SG8230-3D Dynamic Focusing Scanning System was developed for marking in large scan field and small focal spot, integrated the functions of data acquisition, data processing, electronic control, mechanical servo, optical imaging, optical compensation, optical scanning, etc. The control software adopts advanced point by point tracking dynamic compensation algorithm. The system can realize small focal spot, wide range scanning and high flexible laser scanning application
The model SG8230-3D Galvo scanner has the good running stability, high positioning accuracy, faster marking speed, strong anti-interference ability. In the process of dynamic marking, the marking line figures is high precision, distortion free, Power uniform, Pattern without distortion,
the comprehensive performance has reached the international leading level in this field. The advantages are as following:
1. Adopted the most advanced American photoelectric sensor technology and the PDM control mode, combined the Ministry of Aviation developing technology and Military-grade processes and technologies, acquired the independent intellectual property rights.
2. Differential photoelectric sensor for accurate detection of motor rotor position, good linearity, lower drift, high resolution and repeat positioning.
3. Accurate load design for 30mm input aperture mirrors, high accuracy of motor assembly, reasonable structure, very small static friction coefficient and zero offset, all ensured the best dynamic characteristics for the whole system.
4. Drives with advanced detection ability of position and speed, greatly improved the dynamic response performance and scanning speed of the whole system.
5. The whole system adopted the optimization designing of electromagnetic compatibility, with high signal-to-noise ratio and strong anti-interference ability.

6. This scanner system solved the common problems of motor temperature drift, signal interference and zero drift, etc.
