01 — About

What it does

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.

Key features

  • 650nm red laser wavelength
  • 5mW optical output power
  • Operates on 5V DC supply
  • Compact copper head with brass housing for durability
  • Fixed-focus dot beam output
  • Low current draw suitable for microcontroller-driven circuits
  • Simple two-wire connection (VCC and GND)
  • Class IIIa laser classification
  • Easy integration with Arduino, ESP32, and Raspberry Pi

Good to know

  • 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.
