Select the wavelength that best fits your optical or research application at time of purchase.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this laser module come with a battery?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: What does \"adjustable optical coaxiality\" mean?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: What is ACC drive mode and why does it matter?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this module suitable for professional stage or DJ use?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What wavelengths does this adjustable laser diode module support?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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).
