Laser Red Line Module — 650nm, 5mW, Line Beam

Laser Red Line Module — 650nm, 5mW, Line Beam Output for Arduino & DIY Projects

The 650nm red laser line module projects a continuous, straight red laser line rather than a dot — making it the essential component for alignment, leveling, machine vision, and laser scanning applications. The cylindrical lens inside the module spreads the laser beam into a thin, bright line that can be projected across surfaces for precise alignment and measurement.

At 5mW output power and 650nm wavelength (visible red), this module produces a clearly visible red line in normal indoor lighting conditions. The compact module format with standard 3-pin interface (VCC, GND, Signal) makes it easy to integrate into Arduino and microcontroller projects.

Key Features

• Line beam output — cylindrical lens projects a straight laser line rather than a dot
• 650nm wavelength — visible red; clearly visible in normal indoor lighting
• 5mW output power — bright, clearly visible line in indoor environments
• Compact module format — standard 3-pin interface (VCC, GND, Signal)
• Arduino and microcontroller compatible — digital on/off control via GPIO
• Stable, continuous output — consistent line brightness and position

Safety Notice

⚠️ Never point the laser at eyes or reflective surfaces. This is a Class IIIA laser product. Always follow laser safety guidelines when using this module.
