Can you own a Class 3 laser?
Class IIIb lasers cannot legally be promoted as laser pointers or demonstration laser products. Higher powered Class IIIb or IEC Class 3B lasers are dangerous and can cause either temporary visual effects or an eye injury.
What is the highest class laser you can buy?
Worldwide: Laser pointers reach 2000 milliwatts (2 watts)
- The U.S. limit for a laser to be sold as a pointer is 5 mW (0.005 watt).
- The infamous Wicked Laser Spyder III Arctic is nominally a 1000 mW laser (1 watt).
- The most dangerous laser classification, Class 4, begins at 500 mW (1/2 watt) for visible light.
What is a Class 3R laser?
A Class 3R laser is a continuous wave laser, which may produce up to five times the emission limit for Class 1, or Class 2 lasers. Although the MPE can be exceeded, the risk of injury is low. The laser can produce no more than 5 mW in the visible region. Visible class 3R is similar to class IIIA in the US regulations.
What is the most powerful legal laser?
The Spyder III Arctic Wicked Laser is the world’s most powerful handheld laser you can legally own. It is capable of shooting out high-intensity blue lights which can be visible for miles and is even powerful enough to light a match on fire.
Is Blue laser illegal?
Are blue lasers illegal? In the U.S., it is legal under federal law to own a laser of any power. This is somewhat confusing shorthand meaning that the manufacturer or seller illegally called a laser above 5 milliwatts a “pointer”, or illegally promoted it for pointing purposes.

Why are lasers illegal in schools?
The principal of at least one school says he has proof that laser pointers can cause permanent eye damage. The local schools this year also banned laser pointers, according to the mayor.
What are the laser classifications?
Lasers are classified based on their potential for causing injury — especially eye damage, since the eye is most susceptible to excess laser light. There are four main classes for visible-beam lasers: Class 2, Class 3R, Class 3B and Class 4.
What is a Class 3 laser pointer?
Class 3 Laser Pointers . by Gregory Gambone. Laser pointers are available in a wide variety of shapes and sizes, and are typically used as business presentation aids, novelty toys and scientific instrumentation. The technology used in the manufacture of laser pointers has improved in recent years, resulting in significantly more powerful devices.
What are laser categories?
There are three types of lasers: solid state, gas and liquid. While all work according to the same general principles, they are differentiated on the basis of the medium they employ to create the laser action. In solid state lasers, an electrical current pumps electrons into the laser medium – typically…
