Product Description The MXD1230 12mm Red Dot Laser Module is a high-quality, versatile laser diode housed in a durable industrial-grade copper casing. This module is designed to project a concentrated red point (dot) over long distances, making it an essential component for optical experiments, non-contact positioning, and safety alarm systems. Unlike standard fixed-focus modules, the MXD1230 features an adjustable lens that allows the user to fine-tune the spot size or focus the beam at specific distances for maximum precision. Its 3V-5V operating range makes it directly compatible with Arduino, Raspberry Pi, and standard battery packs.
Key Highlights
Adjustable Spot Size: The threaded front lens can be rotated to focus the laser beam into a sharp, tiny point or a wider dot depending on your distance requirements.
Premium Copper Housing: Encased in a 12mm copper shell that provides excellent heat dissipation for the laser diode, ensuring a longer operational lifespan.
Plug-and-Play Compatibility: Works seamlessly with common 3.3V and 5V microcontrollers, requiring no complex driver circuits for basic operation.
Long-Range Visibility: Projects a clear 650nm red beam that remains highly visible even in moderately lit environments.
Industrial Reliability: Built to maintain stable power output (5mW) with low current draw, making it efficient for battery-powered portable devices.

Installation Tip from Robogears While this module is rated up to 5V, we recommend operating it at 3.7V to 4.5V for long-duration use to prevent the diode from overheating. If using with an Arduino, you can trigger the laser via a digital pin, but ensure you include a small current-limiting resistor or use a transistor if powering it for extended periods. Safety Warning: This is a Class 3R/3B type laser; never point the beam at eyes or reflective surfaces, and keep out of reach of children.
