The above calculations are for a 555 nanometer green laser pointer with a tight beam (0.5 milliradian divergence). These parameters are very conservative and thus result in the longest visual interference distances for a Class 3R consumer laser. The more the beam spreads out, the shorter the ...

As of June 2019, this is the most restrictive laser pointer law of any major country; Class 2 pointers (up to 1 milliwatt) are legal in most countries, and Class 3R pointers (up to 5 milliwatts) are legal in the U.S. Travelers should note that laser pointers and "hybrid device...
PLACEMENT:If possible, put this Laser Safety Facts label on the laser device. However, since many Class 3R products such as pointers and handhelds are very small, you can use one of the small labels (below) on the product itself. The Laser Safety Facts label shown above would still be ...
DO NOT USE AS A LASER POINTER Class 3B (and 4) lasers are too powerful to be used as pointers. Some Class 3B (and 4) lasers may look like pointers, but these shouldnotbe used for pointing. Use a Class 2 (less than 1 mW) or Class 3R (less than 5 mW) laser for pointing purpo...
DO NOT USE AS A LASER POINTER Even if this laser looks like a pointer or flashlight,do not use this laser for pointing purposes. Class 4 lasers are too powerful to be used as pointers. Use a Class 2 (less than 1 mW) or Class 3R (less than 5 mW) laser for pointing purposes. ...
