Galvanometer Optical Scanner
The document provides comprehensive technical specifications and application examples for various models of Galvanometer Optical Scanners, including GVM-0930S, GVM-0930L, GVM-1445S, GVM-1445L, GVM-2260, GVM-2280, and GVM-2510. These scanners are utilized in applications such as laser marking, microscopy, image capturing, and high-speed printing.
The scanners are characterized by fast response, low inertia, high torque, high linearity, and positioning accuracy. They also exhibit superior temperature characteristics with minimal effects from humidity.
Each model has specific mechanical and electrical specifications, including maximum scan angle, rotor inertia, coil resistance, inductance, torque constant, back EMF voltage, peak current, and maximum coil temperature. Detailed tables for each model are provided.
The document outlines criteria for selecting scanners and mirrors, including scanning angle, mirror inclusion, cable length, and shaft form. It provides model numbers and configurations for different applications.
Details on mirror substrate materials, recommended coatings, and assembly drawings are included. Reflectance data and mounting angles for optimal performance are provided.
Information on connector pin sequences and dedicated connection cables is included, specifying the function of each pin for proper installation and operation.
Handling precautions are advised to ensure the longevity and performance of the scanners, emphasizing the importance of using the correct driver and mirror combinations.
This guide serves as a technical reference for selecting and implementing Galvanometer Optical Scanners in various industrial and scientific applications.
The document provides detailed specifications and guidelines for the Galvanometer Optical Scanner and its components, including mirrors and servo drivers. It includes information on mirror assembly, coatings, and scanner types.
Mirrors are available in various models (GM0 to GM7) with different laser beam diameters ranging from φ3 to φ30. Substrates are primarily silicon, with coatings such as silver (Ag), gold (Au), and dielectric multilayer for specific laser wavelengths. The choice of coating depends on the laser type, with gold suitable for CO₂ lasers and silver for visible ray lasers.
Detailed drawings of mirror assemblies specify dimensions and mounting instructions. Mirrors can be fixed using screws or adhesive, depending on the model and application.
The GVD series servo drivers offer P and PI control systems. P Control is recommended for applications requiring fast response times, while PI Control is suitable for high position repeatability. Specifications include power voltage, operating current, and protection features.
P Control outputs signals proportional to the differential between position feedback and command signals, offering fast response. PI Control integrates the time of differential, maintaining a stable state with minimal position error.
Precautions for handling the scanner and its components are outlined, emphasizing correct wiring, avoiding excessive stress on cables, and ensuring proper installation to prevent damage.
