About this product
A 5 mW red laser source module that produces a dot-shaped beam with a focus adjustment. It suits alignment, positioning and basic optics or educational projects. Its output is lower than the 50 mW version but it is still a laser, so direct eye exposure must be avoided.

Frequently asked questions
Does the 5 mW module need a current-limited driver?
Yes. Laser diodes should be operated from a constant-current or current-limited driver, not directly from a fixed voltage supply, to avoid damaging the diode.
Is it safe to look at the dot for alignment?
No. Even a low-power laser can damage the eye. Avoid looking into the beam or its reflections, and keep the beam away from eye level.
