Laser Pointers

What Is It?

Laser pointers are used to remotely signify a significant location on a screen or display using a narrow, focused beam of light. Warning: while the light looks harmless, shining a laser pointer directly into a person's eye may damage or even permanently destroy vision.

Laser pointers have several important properties to look at. First, the most visible difference is light color. There are several colors available - red, green, and blue. Second, hybrid pointers with two colors also exist, such as this one with red and green. Lastly, the power output also varies dramatically between different pointers. For example, this bright green pointer is several times brighter (and expensive) than a normal laser pointer.
