Frequently Asked Questions
Q: What power output levels are available for the 450nm blue laser dot module?
A: The Elubor focusable blue laser module is available in three output power options: 100mW, 2W, and 4W. Choose the power level that best suits your application — 100mW for low-intensity precision tasks, 2W for moderate power projects, or 4W for high-intensity stage lighting and engraving applications.
Q: Can this laser module run continuously without overheating?
A: Yes. This module features a built-in cooling fan and an aluminum housing designed for long-duration operation. However, for optimal performance and longevity, ensure the ambient operating temperature remains below 30°C (86°F) and that airflow around the fan is not obstructed.
Q: Does the module support TTL modulation?
A: Yes, the module supports TTL modulation frequency control, making it compatible with CNC laser engraver controllers and other TTL-enabled devices. If you do not require TTL, simply leave the blue and white wires unconnected and power the unit via the red (+) and black (−) wires only.
Q: Is a power supply included with the laser module?
A: The module requires a DC 12V power supply. Please check your selected variant — a DC 12V power adapter may be included depending on the option chosen. The module itself does not include batteries.
Q: What safety precautions should I follow when using this blue laser module?
A: Always wear 450nm wavelength laser safety goggles when the module is in operation. Never point the laser at people, animals, or reflective surfaces. Keep the adjustable lens cap in place to prevent dust contamination of the optics. Review the FDA's laser safety guidelines for comprehensive best practices.
