Frequently Asked Questions
Q: What beam patterns does this 520nm green laser module support?
A: This adjustable laser module supports three beam output modes: Dot, Line, and Cross. The focus can be adjusted to switch between these patterns, making it suitable for a wide range of alignment, positioning, and measurement applications.
Q: What power supply does the Elubor 520nm laser module require?
A: The module operates on DC 2.8V to 5V with a working current of less than 200mA. Batteries are not included; you will need to supply your own DC power source compatible with this voltage range.
Q: How long does this green laser module last?
A: The Elubor QS-1240A is rated for more than 10,000 hours of continuous laser operation, making it a durable and cost-effective choice for long-term industrial or professional use.
Q: What is the difference between 515nm and 520nm laser wavelengths?
A: Both 515nm and 520nm fall within the green visible spectrum. The 520nm wavelength produces a pure, vivid green color that is highly visible to the human eye, which is why it is favored for alignment, stage lighting, and precision measurement applications. This module operates within the 515nm–520nm range for optimal beam clarity and color purity.
