Laser pointer pen for UV inspection

The Hetai Tech 405nm Violet Blue Laser Pointer Pen emits a 405nm wavelength suitable for UV lighting tests and glow thread visibility. It is designed for users who need a portable ultraviolet source for material checks or hobby applications. Buyers who require a visible laser for presentations or long-distance pointing should look elsewhere.

Thermals noise and power draw

The device runs on a 6 volt battery installed with the positive pole toward the tail and the negative pole toward the internal spring. No active cooling or fan is present so operation is silent. Power consumption stays low within the under 5mW output rating and the unit meets Class 3R safety standards.

Questions about this item

How do I install the battery so the positive pole contacts the tail and the negative pole touches the inner spring?

Insert the 6 V cell with its flat end toward the tail cap and the button end against the spring inside the barrel; reversing the cell will prevent the laser from firing.

What maintenance will the 405 nm laser module need over time?

Clean the front lens with a dry microfiber cloth when the beam dims, and replace the 6 V battery once output drops below a usable level.
