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.
Whether you believe it or not, these pointers are representing real dangers to the eyes. 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. When it comes to power output, laser pointers are not actually releasing great amount of power like what you think. If you are a bit skeptical, then try comparing it to the typical light globes which have 75 or 100mW. If that’s the case, how come that these pointers are 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 energy that’s coming from pointers are concentrated on small area like how magnifying glasses work in focusing the sun.
Number 2. Collimated – because of the reason that the light is not spreading from the laser after it’s released, it is what making it a real danger especially when pointed 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. Never look directly into the laser’s beam under any circumstances, even if it’s just a low powered laser. 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. It is because of the reason that the beam can reflect and harm your eyes.
Tip number 4. Like what is said, practice caution when using the laser, preferably only in controlled environment.
Tip number 5. Unless someone who plans to borrow your pointer knows how to use it and dangers that come with them, don’t let anyone borrow it.
If you stick to these guidelines and practice care and common sense, you’ll do fine in using laser pointers.
