650nm Red Laser Diode Module – Focusable Dot Line Cross
650nm Red Laser Diode Module – Focusable Dot Line Cross
650nm Red Laser Diode Module — Focusable Dot, Line & Cross Head
Whether you're building a laser engraver, setting up alignment tools, working on DIY electronics, or designing stage lighting effects, this compact 650nm red laser diode module delivers precision and versatility in a rugged metal housing. Available in five output power levels — 10mW, 30mW, 50mW, 100mW, and 200mW — and three beam patterns (dot, 120° line, and cross), it adapts to a wide range of professional and hobbyist applications.
Key Features
- Multiple Power Options: Choose from 10mW, 30mW, 50mW, 100mW, or 200mW output to match your project's requirements.
- 650nm Red Wavelength: Produces a crisp, visible red beam ideal for alignment, targeting, measurement, and display applications.
- Three Beam Patterns: Easily switch between dot, 120-degree line, and cross projections for maximum versatility.
- Focusable Lens: Adjustable focus lets you dial in a sharp, precise beam at varying distances.
- Compact Mini Form Factor: Slim 12×35mm (or 12×40mm) metal barrel fits neatly into tight enclosures and custom builds.
- Low Voltage Operation: Runs on 3–5V DC at just 30mA — compatible with standard power supplies, Arduino, and Raspberry Pi setups.
- Durable Metal Construction: Silver anodized metal body with plastic lens resists wear for long-term use.
- Wide Operating Temperature: Reliable performance from +10°C to +40°C.

⚠ Laser Safety Notice: This product emits a visible red laser beam. Always follow proper laser safety precautions. Never point a laser at eyes, faces, aircraft, or moving vehicles. Use appropriate laser safety eyewear when working with higher-power (100mW / 200mW) variants. For authoritative laser safety guidelines, refer to the U.S. Consumer Product Safety Commission – Laser Pointer Safety.
Frequently Asked Questions
Q: What beam patterns does this 650nm red laser module support?
A: This focusable laser diode module supports three beam patterns: a focused dot, a wide-angle 120-degree line, and a precise cross pattern. Simply swap or adjust the head to switch between them, making it ideal for alignment, leveling, and projection tasks.
Q: What power supply does the 650nm red laser module require?
A: The module operates on 3–5V DC at approximately 30mA. It is fully compatible with standard regulated DC power supplies, as well as common microcontroller platforms such as Arduino and Raspberry Pi (using appropriate current-limiting resistors at 3.3V outputs).
Q: Can I use this laser module for DIY electronics and maker projects?
A: Absolutely. The compact 12×35mm form factor, low operating voltage, and adjustable focus make this module a popular choice for laser engravers, CNC machines, optical sensors, line-level indicators, educational electronics kits, and professional stage lighting setups.
Q: What is the difference between the 10mW, 50mW, 100mW, and 200mW versions?
A: Higher mW ratings produce a brighter, more visible beam over longer distances and are better suited for industrial alignment or well-lit environments. Lower power options (10mW–30mW) are ideal for close-range projects or light-sensitive setups. Always apply appropriate safety measures for higher-power variants.
