Frequently Asked Questions
Q: What power levels are available for this 650nm red laser diode module?
A: This laser module is available in five power variants: 10mW, 50mW, 100mW, 200mW, and 250mW. Choose the output level that best suits your project requirements — lower power for safe alignment tasks and higher power for more demanding stage or industrial applications.
Q: Can I switch between Dot, Line, and Cross beam patterns?
A: Yes. The module supports three selectable spot modes — Dot, Line, and Cross — making it highly versatile for alignment, measurement, stage lighting, and DIY applications. The specific mode is selected at time of order based on the variant chosen.
Q: What power supply does this laser module require?
A: The module operates on DC 5V, making it compatible with standard USB power adapters and common bench power supplies. It draws between 40mA and 280mA depending on the power variant selected. The included DC cable is 1.2 metres long for convenient reach.
Q: Is the focus adjustable on this laser module?
A: Yes. The module features an adjustable focus mechanism, allowing you to fine-tune the beam sharpness for your specific working distance. This is especially useful for alignment and positioning tasks where a crisp, well-defined spot or line is critical.
