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. These high powered laser pointers are dangers to the eyes despite of its ability to burn and brilliant beams.
These pointers represent 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. In regards to the power output, these laser pointers aren’t releasing as much power as what you think. If you are a bit skeptical, then try comparing it to the typical light globes which have 75 or 100mW. Well, if that is the case, how come these pointers become a danger to one’s eyes? The answer to that lies into 2 unique properties of the pointers.
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.
Well, this isn’t to say that you should feel afraid for using laser pointers but what you must do is to treat it with respect and apply caution when using it. After all, you can avoid dealing with the dangers of these devices easily by just following simple guidelines.
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.
You will be fine in using these laser pointers so long as you stick to these guidelines and practice common sense.
