Laser Pointer & Portable Laser Safety
By Frank Smith

Safety with high powered laser pointers is a critical issue that cannot be overlooked. Despite their brilliant beams and ability to burn, high power laser pointers and portable lasers are only a danger to your eyes. The danger that laser pointers represent to your eyes though is very serious. The visual receptors in your eyes are part of your central nervous system which means if our eyes are damaged, they do not heal or recover. Ever.

As far as power output, laser pointers do not release that much power. Especially not when compared to a normal 75mW or 100mW light globe. What makes the light from laser pointers so dangerous is that it has two unique properties.

1-Coherent and focused. The energy is focused on a very small area similar to the way a magnifying glass focuses the sun

2-Collimated. The light does not spread out from a laser, it stays in a focused narrow beam that makes laser pointers almost as dangerous at a distance as close up.

This not to say you should be afraid of laser pointers or avoid using them. What you should do how ever is to treat laser pointers with respect, be aware of their dangers and follow some basic guidelines to ensure your safety.

Guidelines 1- Never point your laser at another person, especially their face.

2- Never under any circumstances look directly into the laser beam. Even if it is a low powered laser pointer, you don’t want to take chances with your eyes

3- Always be conscious of and aware of reflective surfaces such as mirrors, polished metal or glass. A reflected beam can also harm your eyes.

4- Only use laser pointers in a controlled environment

5- Do not let other people use your laser pointer unless they are fully aware of the dangers of laser pointers

6- Laser pointer beams can go for miles so never randomly use your laser pointer outside

If you adhere to these guidelines and exercise simple common sense and care, you will be able enjoy and use your laser pointers in complete safety.
