Best Laser Pointer For Your Presentation

By Edgar Hernandez

Laser pointers are very useful during presentations, allowing the speaker to point important areas on the display screen from across the room. Red laser pointers are the most common type and use a lower powered light, normally a 650nm wavelength. You can get a common red laser pointer for less than $20 today. Green laser pointers have recently become more popular and are powered by a more powerful laser (usually a 532nm wavelength), making them much more visible that red lasers. Some green laser pointers are more than 50 times more powerful than the red ones, and can even burn paper and cast a visible beam even in a lighted room. The low-end green laser pointers start at about $50 and can go up to several hundred dollars for a more high powered one. We use Green laser pointer on our presentation and they work great they are brighter than the Red lasers and are easier to follow on the screen.

Now since Green lasers are more powerful than the Red one, it is important to keep in mind that people have been arrested for pointing them at planes, at people at sporting events, and at or around law enforcement officers. So use them wisely – laser pointers ARE NOT toys and should not be used in away to cause damage to people or property.
