Laser Pointer
Can a class 3B laser pointer damage my eyes?
I recently aquired a class 3b laser pointer from ebay. It runs at 1mw, and so I believe it is a very weak laser. I read online that class 3B lasers can cause instant damage to your eyes, yet it was talking about 3B lasers up to the power of 500mw (500 times the power of mine). Can anyone help me out here and tell me if there is any risk with even momentary, direct exposure to the eye from the laser?
Thanks in advance,
Tom
If your laser is a visible laser at 1 mW, it is not a class 3B laser. That would be a class 2 laser. However, the class is more important than the power. The class will take into account the wavelength as well. You should treat all class 3B lasers as if they can damage your eye instantly.
It sounds like either you do not know the power of your laser or you are misreading the laser class. For example, if your laser is green, there is a good chance that is is a doubled IR laser, and IR lasers are more dangerous than visible lasers of the same power (because you can't see them and your blink reflex does not respond to invisible lasers).
On a side note, class 2 lasers (even 1 mW visible lasers) can damage vision and count on your blink reflex to provide protection.
My recommendation is to pay more attention to the class of your laser than the power of your laser. If you are a laser expert, you can more easily identify the dangers of your particular laser.
