Product Description

Add a precision pointing element to your builds with the 650nm 5V Mini Laser Dot Diode Module. This ultra-compact laser diode is designed for easy integration into low-power electronics and robotics. At Robogears, we recommend this module for its stable 5mW output, which provides a bright, clearly visible red dot even in well-lit indoor environments. Housed in a durable 6mm copper casing, it acts as its own heatsink for short-duration tasks. Whether you are building a laser-tripwire security system, a long-range optical communicator, or a laser-guided robot at your Pimpri facility, this 5V module offers a simple plug-and-play solution for your optical needs.

Detailed Key Features

  • Compact 6mm Form Factor: The miniature cylindrical design allows it to be embedded into small enclosures, 3D-printed mounts, or even handheld devices.

  • Low Power Consumption: Drawing less than 40mA, it can be powered directly from the 5V pin of an Arduino or Raspberry Pi without an external driver.

  • Integrated Current Limiting: Features internal circuitry to protect the diode, though a series resistor can be added for extra safety during long-term continuous use.

  • Focused Dot Beam: Emits a concentrated red beam with a 650nm wavelength, ideal for precise alignment and targeting applications.

  • Industrial Copper Housing: The metal casing provides physical protection and basic thermal management for the sensitive laser diode.

All Technical Details

  • Wiring: Typically comes with pre-soldered flexible leads (Red for +5V, Blue/Black for Ground).

  • Visibility: Red dot is visible up to several dozen meters in low light (visibility depends on ambient light and atmospheric conditions).

  • Mounting: Can be press-fitted into a 6mm hole or secured with a small set screw.

  • Applications: DIY laser pointers, electronic security fences, target positioning, and light-beam sensors.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Laser Safety First: At our Pimpri workshop, we remind all makers: NEVER look directly into the laser beam or point it at people or animals. Even at 5mW, direct eye exposure can cause permanent damage.

  • Duty Cycle Management: While the copper casing helps, the diode can overheat if left on for hours. For security systems, consider "pulsing" the laser (turning it on for 10ms every 100ms) to extend its lifespan.

  • Optical Alignment: If the dot appears "fuzzy," check the lens for dust. Clean it gently with a dry cotton swab. Do not use harsh chemicals as they may cloud the plastic lens.

  • Pairing with LDRs: For a laser tripwire, pair this diode with a Photoresistor (LDR) inside a black tube. This setup ensures the LDR only "sees" the laser dot and isn't triggered by ambient room light.

Package Includes

  • 1 x 650nm 6mm 5V DC 5mW Mini Laser Dot Diode Module
