Abstract
A laser pen for illuminating a workpiece is provided including a pen body, a pen head secured to the pen body, and a laser generator accommodated in the pen head. The laser generator can emit a laser light. The measuring member is rotatable relative to the pen body and includes a graduated disk and a measuring disk. The graduated disk defines a circle of graduated sections, at least one of which is exposed out of the pen head. The measuring disk defines a circle of continuous through holes with different sizes. The measuring member coupled with the graduated disk can rotate relative to the pen body to align each one of the through holes with the laser generator, to adjust the amount of laser light passing through the one of the through holes and striking on the workpiece.
