The progression of laser technology brings with it immense benefits for medical, industrial, and entertainment use. However, powerful technology also presents risks. This ease of acquisition increases the opportunities for misuse, either intentional or accidental.
Powerful laser products are becoming easier and cheaper to obtain for the general public. One such laser product is your BluRay player. Your device uses a powerful laser to read the information encoded on your disk and play the media.
There are several risks associated with laser products:
- Lasers can damage sight if they come in contact with the eyes. Laser is concentrated light, might stronger than any natural light that may enter your eye. This means they can easily burn the eye and cause sight loss.
- Invisible infra-red light can also be a hazard. Some low quality lasers can emit dangerous levels of infra red light while only appearing to emit low levels of light. This is particularly dangerous because the risk is not apparent.
- Stronger lasers can cause burns to the other, more resilent parts of the body. These should be handled with extreme caution.
We consulted Dave from WA Electrical in Perth about the risks posed by the lasers in BluRay players. He assures us that for well made products the risk is minimal. The lasers are safely installed and extremely hard to remove withough rendering them non-functional. These lasers also have to adhere to strict industry standards for safety.
As with all electronic devices however, ensure you always purchase quality brands and excercise caution when bring back cheap devices from overseas.
