10 Pieces 5V 650nm 6mm 5mW Mini Laser Dot Diode Module Copper Head Red The laser emission principle and manufacturing process give lasers unique characteristics compared to ordinary light, including high brightness, good color, coherence, and directionality. Commonly used in laser pointers, leveling tools, and various instrumentation applications. Ideal for creating electronic pointer pens—teachers can use the laser dot to direct attention during lectures for better observation and engagement. Laser safety is important. Never point the laser at anyone's eyes, even when the device is turned off. Avoid shining the laser on reflective or smooth surfaces, as reflections can cause eye injury. This product is not a toy and should not be given to children or individuals unable to understand safe usage. Use appropriate laser safety goggles, especially when working with invisible lasers. Do not carry lasers on airplanes, vehicles, or into restricted areas. Pay attention to battery safety. Prevent short circuits, overheating, or battery damage by avoiding improper handling or disassembly.
