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 of its ability to burn and brilliant beams, these high powered laser pointers as well as portable laser are a danger to the eyes.
Whether you believe it or not, these pointers are representing real dangers to the eyes. 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. Well, if that is the case, how come these pointers become a danger to one’s eyes? The 2 unique properties of the pointer is where you will find the answer to this question.
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 doesn’t spread after it is released from the laser rather, it stays focused in narrow beam which makes these lasers to be a real danger at a close distance.
This doesn’t literally say that you must steer clear from using laser pointers rather, you have to learn how to treat it right and carefully. 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. 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. It is your job to be conscious of your surroundings and check if there are reflected surfaces like glass, mirrors or metal polished; if there are, then don’t use your laser pointers. 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.
