When making a presentation our objective is to create an impression on the minds our audience with the message that we are delivering. But the message on its own cannot have the effect that you would like to achieve if it is presented in a sloppy manner. That is to say you cannot have a good presenter, presenting with inferior equipment and expect to get the desired outcome that you intended in the first place.
Since the laser pointer playing such a important role in your presentation, choosing a right laser pointer will be of importance. Let me share with you some practical tips on how to select the right laser pointer which suits your needs most:
The color of laser pointer
Different lasers come with different colors, such as red, blue, green and yellow. Different colors have different wavelength. You need to decide on the wavelength or color before you purchase a pointer. Red lasers are usually the weakest with the wavelength of 632nm. Due to this reason, the cost of getting a red laser is always the lowest. Green laser is stronger than red laser with the wavelength of 532nm. The most expensive and strongest pointer is the blue pointer with the wavelength of 473nm. Yellow is considered a unique color. If you want to make yourself different, you are recommended to get a yellow pointer which comes with the wavelength of 593.5nm.
The batteries used
In general, most of the laser pointers in the market require triple A batteries. You are reminded not to choose those pointers which require special batteries. Since Less common batteries are hard to find,you may have difficulty replacing the batteries. There is nothing more irritating than running out of battery power for your pointer in the middle of a presentation if you fail to get spare batteries on time.
The output power
How powerful you want your laser pointer to be? It depends much on what you want to show to your audience. To be frank, a low output power, say 1mW, is ideal for indoor use. It works well for presentation in the meeting rooms or seminar halls. If you need the pointer to be used in a large room, you may need to try those with output power at around 2-5mW. You have to bear in mind that any laser with an output power of greater than 5mW is harmful to bodies by directly pointing it to people or pets. Some countries do not allow citizen use laser which output is greater then 5mW,like United States.Keep in mind that never shoot the laser to people and animals.
Although the cost of getting this tool is not very high, it is better for you to spend some time to find the right one for yourself so that you can achieve great success in your PowerPoint presentation.
