FAQs about Laser Pointers
Laser pointers are small devices that produce lasers which are usually used in boardroom or classroom situations. These useful electronics use a small beam of light to highlight things of interest. Like their name suggests, they use lasers to point at things. Although the beam from a laser pointer cannot be seen from the side, it can be visible if dust or other particles are scattered in the path of the light. Most of the light remains focused on a point at the end of the beam, making lasers perfect for pointing at objects.
