Basic Info Before Using Laser Pointers
It’s a big concern in the public to apply caution when using high powered laser pointers and something that just can’t be overlooked. 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. Your eye’s visual receptors are part of the central nervous systems meaning, if your eyes gets damaged, then they wouldn’t be able to recover or heal. When it comes to power output, laser pointers are not actually releasing great amount of power like what you think. This is true most especially if you try comparing it to the typical 75 or 100mW light globe. With this being said, you may be wondering on how these pointers are danger to the 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 way how the energy is released from these pointers follow the same principle as what magnifying glasses do in 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 should never dare to point the laser at any person most especially directly into their eyes.
Tip number 2. Don’t look directly to the beam of the laser under any circumstances, even if it is only a low powered laser. No one wanted to lose their vision of course, so why would you dare to take your chances in doing such thing.
Tip number 3. You have to be aware and conscious of the reflective surfaces when using your laser pointers similar to glass, polished metal or mirrors. The reason for this is that, the beam will bounce back and damage your eyes.
Tip number 4. Consider to only use the laser when you are in a controlled place because like what’s mentioned earlier, you have to apply caution when using it.
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.
You will be fine in using these laser pointers so long as you stick to these guidelines and practice common sense.
