Presentation of the equipment's characteristics

The LC2820-GST High-Power Galvo Scanner is a precision, water-cooled galvanometer scanning system designed for high-power laser applications requiring stable operation and strong noise immunity. Optimized for up to 2000 W continuous-wave (CW) fiber lasers, it features a 20 mm laser input aperture and delivers fast dynamic response, high linearity, and low drift for consistent scanning performance.

To match different laser beam divergence parameters, the system can be configured with the appropriate QBH beam expander/collimation module and a high-power quartz F-theta field lens, enabling reliable operation in industrial laser cleaning and related surface processing environments.

processed samples

  • Differential photoelectric position feedback (high accuracy control)
    Differential photoelectric sensing precisely detects rotor position, supporting excellent linearity, low drift, high resolution, and high repeatability.

  • Precision load design for 20 mm mirrors
    Optimized mechanical structure and high-accuracy motor assembly for 20 mm scan mirrors. Low static friction and reduced zero-position drift help ensure strong dynamic characteristics.

  • Position & speed over-limit monitoring
    Integrated driver protection functions for position and speed threshold detection help improve system dynamic response and scanning speed.

  • Multiple protections for stable uptime
    Built-in overload, overcurrent, and reverse-polarity protection improve reliability and reduce risk in industrial operation.

  • EMC-optimized design for strong anti-interference
    System-level electromagnetic compatibility optimization delivers high signal integrity and excellent resistance to electrical noise in complex factory environments.
