π¦ What is a Laser Pen?
A Laser Light Pen is a small electronic device that emits a bright and focused laser beam. This beam creates a clear and bright dot on any distant object, making it easy to explain or point to things.
It is also commonly called a Laser Pointer Pen because of its pen-like shape.
βοΈ How does a Light Pen work?
A Laser Light Pen mainly consists of three things:
- Laser Diode β which produces the laser light
- Battery β for power
- Switch/Button β for on/off
When you press the button, power from the battery is directed to the laser diode, and a concentrated light beam is emitted, traveling in a straight line over a long distance.
