Frequently Asked Questions
Q: What beam shapes do these 405nm laser diode modules support?
A: Each focusable laser module can produce three beam shapes: a precise dot, a line at 120 degrees, or a cross pattern, depending on the lens configuration selected. This makes them highly adaptable for various DIY and professional applications.
Q: What power output options are available for these violet blue laser modules?
A: These 405nm laser modules are available in three output power levels: 10mW, 20mW, and 50mW. Choose the power level that best suits your project requirements — lower power for sensing and alignment, higher power for more visible stage or display effects.
Q: Are these laser modules compatible with Arduino and Raspberry Pi projects?
A: Yes! With a working voltage of 3–5V DC, these laser diode modules are perfectly compatible with Arduino, Raspberry Pi, and most other microcontroller platforms, making them a great choice for electronics hobbyists and engineers.
Q: How many modules are included in one purchase?
A: Each purchase includes a pack of 5 focusable 405nm violet blue laser diode modules, giving you extras for prototyping, testing, or multi-beam setups.
