The adjustable focus head gives you flexibility for both close-range and mid-range applications. Operating at a low 3V DC makes them compatible with a wide range of microcontrollers and battery-powered circuits. With five units per pack, you'll always have spares on hand for prototyping and production.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMade in Mainland China.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e⚠️ \u003cstrong\u003eLaser Safety Notice:\u003c\/strong\u003e Do not point directly at eyes or skin.

You may notice a faint red glow at the emitter, but the beam itself is largely invisible without an IR-sensitive camera or viewer. This is perfectly normal behavior for a 780nm laser module.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What voltage and current do these IR laser dot modules require?\u003c\/h4\u003e\n\u003cp\u003eA: Each module operates at 3V DC with a working current of less than 40mA, making them ideal for use with common microcontroller boards, coin cells, or small regulated power supplies.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these laser modules focusable?\u003c\/h4\u003e\n\u003cp\u003eA: Yes.
