Frequently Asked Questions

Q: What wavelengths does this adjustable laser diode module support?

A: This LD module is available in a wide range of wavelengths: violet-to-blue (405 / 450 / 475 / 480 / 488 nm), green (505 / 510 / 520 nm), and red (635 / 650 / 658 / 660 nm). Select the wavelength that best fits your optical or research application at time of purchase.

Q: Does this laser module come with a battery?

A: No, the 10440 lithium battery (350 mAh, 3.7V DC) is NOT included due to customs clearance restrictions. However, a charger is included in the package so you can power up as soon as your battery arrives.

Q: What does "adjustable optical coaxiality" mean?

A: The concentric pen coaxial design allows you to fine-tune the alignment between the laser diode and the optical axis of the module. This ensures a precise, centered beam output — critical for optical experiments, alignment tasks, and any application requiring high pointing accuracy.

Q: What is ACC drive mode and why does it matter?

A: ACC stands for Automatic Current Control. This drive mode regulates the electrical current delivered to the laser diode automatically, ensuring stable and consistent laser output regardless of minor voltage fluctuations — extending the life of the diode and maintaining reliable performance.

Q: Is this module suitable for professional stage or DJ use?

A: Yes. The compact stainless steel pen form factor and precise dot beam make this module well-suited for professional stage setups, DJ lighting rigs, and other performance environments that require a focused, high-quality laser point source.
