A Simple Guide Prior To Using Laser Pointers
Safety using high powered laser pointers is a big concern among public and something that can’t be disregarded. Despite its brilliant beams, the use of high powered laser pointers and portable lasers as well can bring dangers to the eyes.
The danger that these pointers represent into your eyes are no laughing matter. The visual receptors of your eyes are part of central nervous system which means that if it gets damaged, then they would not be able to heal or recover. In regards to the power output, these laser pointers aren’t releasing as much power as what you think. This is true most especially if you try comparing it to the typical 75 or 100mW light globe. Well, if that is the case, how come these pointers become a danger to one’s eyes? As a matter of fact, the answer to this question lies in the pointer’s 2 unique properties.
Number. 1 focused and coherent – the energy coming from the pointers are concentrated on a very small area much like the way how a magnifying glass is focusing the sun.
Number 2. Collimated – the light does not spread even after it’s beamed out from the laser instead, it stays in a narrow line making the lasers to be a real threat especially at close distance.
This not to say that you have to be afraid of using laser pointers but what you should do however is, treat it with respect and use it cautiously. In the end, by following simple guidelines, you can ensure that everyone’s safe and avoid the dangers of such.
Tip number 1. You must not point the laser to anyone even if it’s just horseplay, more so not point it directly in their eyes.
Tip number 2. Even if the laser is said to be of low power, you should not look into the beam directly. Probably, you don’t like to take your chances, considering that it may potentially damage your vision.
Tip number 3. You must be aware and conscious of reflective surfaces around you when using laser pointers like polished metals, mirrors or even glass. The reason for this is that, the beam will bounce back and damage your eyes.
Tip number 4. Like what is said, practice caution when using the laser, preferably only in controlled environment.
Tip number 5. You should not let others to use the pointer unless, they know how to and has knowledge of the dangers that come with such device.
If you stick to these guidelines and practice care and common sense, you’ll do fine in using laser pointers.
