AF8210 Auto-focusing Scanning System

The model AF8210 galvo scanner has the good running stability, high positioning accuracy, fast marking speed, strong anti-interference ability, the overall performance of AF8210 has reached the international leading level in this field. 


The advantages are as following:


■ Adopted the photoelectric sensors which imported from America, and owned the proprietary intellectual property rights.

■ Differential photoelectric sensor for accurate detection of motor rotor position, good linearity, lower drift, high resolution and repeat positioning.

■ Accurate load design for 10 mm 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.

■ Design of overload, over-current and reverse connect protection, makes the system running more reliable.

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

■ Auto-focusing mode, one key for positioning to the default focus height quickly, improving the operation efficiency.
