Direct or indirect skin exposure to blue laser light is also harmful. The MPE (Maximum Permissible Exposure) for skin for a 3mm beam of this wavelength is approximately 200mW/CM^2. This is laser can easily generate a power density (irradiance) of about 15 Watts/CM^2. Therefore, this laser's beam exceeds the skin exposure MPE by ( 15 / 0.2 ) = 75 times. At this level of irradiance, skin exposure to the intense blue laser light can possibly cause cancer. Do not allow bare skin to be exposed, including your face when wearing safety goggles, to light diffusely reflected from any surface closer than several inches. This laser is a thousand times stronger than sunlight on skin and any type of exposure should be avoided whether it be from the collimated beam or close exposure to its bright diffused reflections.

Basically this can give you cancer! better wear safety goggles

Blue light hazard can cause BLINDNESS and not just color perception issues. The power of this laser is no joke, at 1W the Spyder III Pro Arctic is a Class 4 Laser. Do not allow unprotected eye exposure to diffusely scattered light from the beam terminating on a wall, the floor or other flat surface from this laser closer than 3 feet. Accidental eye exposure will definitely result in instant retina tissue damage even within just milliseconds of exposure. Direct eye contact with the beam or reflected will cause instant permanent damage and blindness. Sometimes blindness may take a day or longer for the onset. Unlike instant injury from a bright flash of a red or green laser, this effect is cumulative over 24 hours. It is also possible that such an exposure could cause retinal degeneration and even loss of vision later in life

Isn't this cool!?

Sounds like its from a laser projector or something... Cant think of why else someone would want a cancer causing blue laser.

I went to the website... it is, and its $2000. And the projector sounds really neat

[dragonhead]

it wont just cause cancer. it will incinerate your skin instantly, and cause complete permanent blindness in less that a quarter of a second at anything less than 300ft. the reflection of the beam off of a matte black surface will cause blindness almost instantly. the reflection off a mildly shiny object a quarter mile away will cause blindness is less than a second.

Indeed. Class 4 lasers can damage eyesight even if you are in the same room. Sunglasses won't cut it.

hence the awesomeness!

hey im a professional

...now how do you turn this thing on...
maybe if i look into the end it will help

that would be like pointing a loaded gun at your face. would you think that was funny?

[humakabula1]

hey, hey i never said to actually do that!
and i have a strange sense of humour

Now on a more serious note;

THIS LASER IS NOT A TOY AND SHOULD ONLY BE HANDLED BY PROFESSIONALS IN A CONTROLLED ENVIRONMENT

1 - Do not allow minors to use a handheld laser unsupervised. Furthermore, only allow adults to use laser pointers after they have understood the responsibilities and risks that it carries.
2 - Never shine a laser at anyone, especially their face. Even temporary exposure can cause significant damage to the eye. Lasers are designed to point at inanimate objects.
3 - Always be conscious of where you're pointing. Avoid pointing a laser at any reflective surfaces. Unintentionally reflected beams can easily violate laser safety tip #2.
4 - Never use your laser in the vicinity of airports, highways, construction sites or anywhere individuals need to constantly pay attention to their work for their own safety. A split-second distraction, a sudden laser light in a plane cockpit, for example, can be disastrous.
5 - Be especially cautious around high-powered lasers, like green handheld lasers used for stargazing. They are far stronger than the conventional red lasers commonly used during lectures. And do not purchase a handheld laser at all if it does not identify its class or power.

Thats pretty cool.
But the caption for the vid says "dont substitue laser goggles with sunglasses"
The goggles are much MUCH bette but it still says that you still shouldnt point at the eye
even if the person is wearing the goggles

Anyone know how a welding helmet would do against a laser of that power?

[thewise1]

I'm taking kind of a shot in the dark here but isn't a welding helmet lens just a tinted lens, just blocking light. Not meant for blocking radiation.

Light=radiation. I think welding gives off UV rays (too lazy to check wikipedia).
