520nm 20mW Green Straight Line Laser Module for Laser Positioning Indication

520nm 20mW Green Straight Line Laser Module for Laser Positioning Indication The 520nm 20mW Green Straight Line Laser Module—a precision positioning solution engineered for laser positioning indication across industrial, commercial, and construction scenarios. Leveraging 520nm green lasers’ superior visibility, 20mW stable linear output, and ultra-clear straight line projection, this module delivers accurate, reliable positioning guidance for alignment, marking, and calibration tasks. Core Advantages for Positioning Indication 520nm Green Wavelength: Ultra-High Visibility 520nm green light offers 3–5x higher perceived brightness than red lasers at the same power, standing out sharply in indoor/outdoor environments (even under bright ambient light); ideal for long-distance positioning and high-precision alignment needs. 20mW Stable Output: Reliable Performance CW mode output with lower power fluctuation guarantees long-term stability; 20mW power balances brightness and safety (Class 3B compliant), avoiding eye strain while maintaining clear visibility for extended use. Key Applications Industrial Positioning: Assembly line part alignment, CNC machine workbench marking, conveyor belt edge positioning, and laser cutting/engraving guide lines. Construction & Decoration: Wall/floor leveling, tile laying alignment, suspended ceiling installation marking, and architectural layout calibration. Automation & Robotics: AGV path indication, robotic arm working area marking, and automated production line positioning. Commercial & Daily Use: Retail shelf alignment, exhibition booth setup marking, and home improvement tools (drill guide, sawing line indication).
