5-Pack 780nm IR Laser Dot Module 3V 5mW Focusable 6mm
5-Pack 780nm IR Laser Dot Module 3V 5mW Focusable 6mm
5-Pack Focusable 780nm Infrared Laser Dot Modules — Compact, Precise & Versatile
Get five compact infrared (IR) laser dot modules in one convenient set. Each module emits a near-infrared 780nm wavelength beam at 5mW output power, housed in a durable brass body measuring just 6mm × 10mm. The adjustable focus lets you dial in a sharp dot for sensing, alignment, detection, and DIY electronics projects with ease.
Please Note: 780nm is a near-infrared wavelength. Only a faint red glow may be visible to the naked eye — this is completely normal and expected for IR lasers.

Frequently Asked Questions
Q: Can I see the 780nm IR laser beam with the naked eye?
A: Only barely. 780nm sits at the very edge of the near-infrared spectrum. 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.
Q: What voltage and current do these IR laser dot modules require?
A: 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.
Q: Are these laser modules focusable?
A: Yes. Each module features an adjustable focus head so you can fine-tune the dot sharpness for your specific distance and application requirements.
Q: What is the beam diameter at distance?
A: The beam diverges to approximately 10–15mm in diameter at a distance of 15 meters, making these suitable for both short-range precision work and longer-range sensing setups.
