The 3V 9mm Copper Laser Module is a high-power, versatile optical device designed for professional alignment, industrial positioning, and precision targeting applications. With 50mW output power, a 650nm red wavelength, and selectable dot, cross, or line beam patterns, this module delivers exceptional brightness and flexibility. The 9mm copper housing provides superior heat dissipation, making it suitable for continuous-duty industrial use.
At the heart of the module is a 50mW red laser diode operating at 650nm, producing a highly visible red beam that remains clear even in brightly lit environments. Unlike standard 5mW modules, the 50mW output provides significantly greater brightness and range, making it suitable for outdoor applications, long-distance alignment, and industrial measurement tasks where a standard laser would be difficult to see.
The module offers three selectable beam patterns — Dot, Cross, and Line — allowing you to choose the optimal projection for your specific application. The dot pattern is ideal for precision aiming and targeting. The cross pattern provides two-axis alignment for centering and leveling. The line pattern is perfect for cutting guides, straight-edge alignment, and positioning tasks. The beam pattern is selected based on the specific module variant ordered.
The 9mm copper housing is a key feature of this module. Copper’s high thermal conductivity efficiently dissipates the heat generated by the 50mW laser diode, ensuring stable output, consistent brightness, and extended lifespan even during continuous operation. The larger 9mm diameter also provides a more robust, industrial-grade form factor compared to standard 6mm modules.
The module operates from a 3V DC supply, making it compatible with 2×AA or 2×AAA battery configurations and other low-voltage power sources. A built-in driver circuit regulates the current to the laser diode, ensuring stable output and protecting the diode from current spikes. The low voltage requirement makes this module particularly suitable for battery-powered portable devices and compact industrial equipment.
Important Safety Note: This is a Class 3B laser product (50mW). Direct eye exposure to the beam is hazardous. Do not stare directly into the laser beam or point it at people, animals, or reflective surfaces. Laser safety glasses are mandatory when operating this module. Keep out of reach of children. The module should be mounted securely and operated only by trained individuals who understand Class 3B laser safety precautions.
Whether you are building an industrial alignment system, a precision targeting device, or a professional-grade laser level, the 3V 9mm Copper Laser Module provides the power, flexibility, and reliability you need. It is suitable for engineers, industrial integrators, and businesses purchasing in bulk for product development or industrial applications.
