Laser Diode 650nm Red – 5mW Point Laser Module

The 650nm Red Laser Diode is a compact, low-power laser module that emits a focused red dot beam at a 650nm wavelength. Housed in a durable copper head casing, it operates on a standard 5V supply and is widely used in Arduino, Raspberry Pi, and embedded electronics projects for pointing, sensing, alignment, and object detection applications.

Important Notes

• Never point the laser directly into eyes; direct or reflected beam exposure can cause eye damage.
• Operate strictly within the rated voltage range to avoid damaging the laser diode.
• Avoid prolonged continuous operation without adequate heat dissipation.
• Keep away from children and use only for intended educational or project purposes.
• Do not disassemble or attempt to modify the internal laser diode assembly.
• Handle with care; laser diodes are sensitive to static discharge and mechanical shock.
