650nm 5mW Red Line Laser Diode Module – Adjustable Focus, 120° Fan Angle

Achieve precise alignment and accurate visual guides in your DIY or professional projects with this 5mW red line laser module. Emitting a bright 650nm red laser in a crisp, focused line, this compact Class IIIa laser is ideal for marking, leveling, cutting guides, positioning, and more. Designed for ease of use and durability, the module comes fully assembled in a chrome-plated brass housing that resists wear and provides excellent heat dissipation. The integrated driver circuitry makes it plug-and-play with a simple 5V DC power connection—no external components needed. At the front, an adjustable focus ring lets you fine-tune the line’s sharpness and coverage for different distances or materials. Rotating the lens also adjusts the direction of the line, making it ideal for both horizontal and vertical alignment tasks. ⚠️ Important Note: The case is not electrically isolated—it is tied to the laser diode’s anode and will be at the same voltage as your power supply.
