Galvanometer Optical Scanner
This 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 distinct mechanical and electrical specifications, including maximum scan angle, rotor inertia, coil resistance, and torque constant. Detailed tables for each model are provided.
Models are chosen based on scanning angle, mirror inclusion, cable length, and shaft form. Custom options are available for specific needs.
Mirrors are selected based on substrate material, coating, and assembly. Reflectance data and assembly drawings are included.
Details on connector pin sequences and dedicated connection cables are provided for each model.
Handling precautions and notes on specifications emphasize the importance of using the correct driver and mirror combinations.
The document serves as a comprehensive guide for selecting and using Galvanometer Optical Scanners, providing all necessary technical details and application guidance.
This section provides detailed specifications and guidelines for the Galvanometer Optical Scanner and its components, including mirrors and servo drivers. It covers mirror assembly, coating options, scanner types, and control systems.
Reflectance data for mirrors at a 45° incident angle is outlined, with graphs showing reflectance percentages across different wavelengths. Mirror models, laser beam diameters, substrates, and recommended coatings are specified. Coating options include Gold (Au) for CO₂ lasers, Silver (Ag) for visible ray lasers, and Dielectric Multilayer Coating for YAG lasers.
Details on mirror assembly drawings and mounting angles are provided. Mechanical angles for different laser diameters are specified, with advice to contact sales representatives for angles exceeding ±10°.
The GVD Series servo drivers offer P Control and PI Control systems. P Control is suitable for high-speed settling, while PI Control ensures high position repeatability. Specifications for different models (GVD0, GVD1, GVD2) include power voltage, operating current, input impedance, and protection features.
Specifications for galvanometer optical scanners and drivers include power voltage, maximum operating current, peak current, input/output signals, and ambient temperature range. External layout drawings with dimensions are also provided.
Proper handling and installation are emphasized to prevent damage or malfunction. Cautions for wiring, handling precision parts, and environmental conditions are included. A warranty section outlines terms for product repair within one year of delivery.
Definitions for terms like non-linearity, offset drift, thermal drift, and step response time are provided, explaining their significance in scanner performance.
Defects caused by misuse or mishandling, or those occurring more than one year after delivery, are the customer's responsibility for repair charges. Repairs are conducted at the company's location, with the customer covering shipping costs. The company is not liable for transit damages, and products should be packed with adequate cushioning.
