Galvo Scanner

Galvo Resonant Scanner

The single-axis galvo motor system contains a high-precision sensor and a motor part based on moving magnet technology. The motor rotor is optimized for excellent dynamic properties and response characteristics. In addition, the motor features high rigidity and low friction. Moreover, each motor is matched to a certain inertia mirror through the kinematics and dynamics simulation.

Galvo Scanner Wiki

The galvanometer parts of photoelectric analog xy galvanometer and grating digital galvanometer are similar, the biggest analog and digital system difference is using different encoders. The photoelectric analog galvanometer uses the photoelectric encoder. When the galvanometer drives the baffle to rotate, the area covered by the baffle will change, and the photocurrent generated will also change. Thus the corresponding relation between the photocurrent and the galvanometer deflection Angle is formed. Grating digital galvanometer uses grating encoder. When the galvanometer drives the grating size to rotate, Sin/Cos signals will be generated on the reading head. The phase of Sin/Cos signals are corresponding to the deflection Angle of the galvanometer.

How To Maintain My Laser Single Axis Galvo Scanner Well

The repair and maintenance of all parts of this scanner head must be performed by Shenzhen Hans Scanner S&T CO., Ltd. Only Shenzhen Han’s Scanner S&T CO., Ltd. has the correct test standards and correction system. The mirrors need to be regularly cleaned because the dirty mirrors would absorb the laser energy and interfere with the mirrors. Check the mirrors regularly, if they are dirty clean the laser galvo mirror as follows. Wearing a cotton glove, hold the edge of the mirrors, keep the optical emission surface face up and use clean compressed air to blow the mirrors to remove dust, dirt, etc. For storage, use, and service, please make sure: Storage temperature: -35°C to +60°C , Use temperature: 25°C ±10°C, Avoid damp or corrosion.
