Red Copper Laser Diode Module 650nm 9mm 3V 50mW (Line / Point / Cross)

Enhance your precision alignment, targeting, and optical DIY projects with this High-Performance Red Copper Laser Diode Module! Operating at a standard 650nm visible red wavelength with a powerful 50mW output, this 9mm optical module is housed in a heavy-duty copper casing that provides superior heat dissipation for long-term operational stability. Powered by a convenient 3V DC supply, it is available in Line, Point (Dot), and Crosshair beam projection options to suit a wide range of applications. Whether you need a crisp alignment cross for woodworking machinery, a focus dot for positioning systems, or a line projector for leveling tools, this compact module delivers bright, razor-sharp red laser projections.

Key Features

• Heavy-duty red copper housing solid copper body ensures excellent thermal conductivity to protect the internal diode from overheating

• Available in 3 beam pattern options choose between Point (Dot), Line, or Cross projection models for specialized alignment tasks

• Bright 650nm 50mW red optical beam provides strong visual clarity for indoor positioning, leveling, and optical experiments

• Safe 3V DC working voltage easily powered by 2x AA batteries, coin cells, or low-voltage DC power supplies

• Compact 9mm outer diameter low-profile cylindrical shape drops effortlessly into custom machine mounts, sights, and 3D prints

Why Choose Our Copper Laser Diode Module

Standard aluminum or plastic laser modules suffer from rapid heat accumulation that degrades diode brightness and reduces service life. The solid copper construction of this 9mm laser module rapidly pulls heat away from the semiconductor junction, maintaining steady beam brightness and long-term durability during continuous operation.

Perfect For

• Industrial machinery alignment, woodworking saw guide projection, and tile/masonry leveling

• DIY laser engravers, 3D scanner alignment, robotics sensing, and laboratory optics experiments

• Custom targeting sights, optical instruments, and electronic hobbyist projects
