Laser pointers typically have an output beam power of less than 5 milliwatts (<5 mW). They fall under Class II or Class IIIa laser classifications.
Here's a breakdown of laser pointer strength and safety:
-
Power Levels: In the United States, laser pointers are generally restricted to less than 5 milliwatts to minimize potential eye hazards.
-
Classification: Laser pointers are classified based on their power output. Common classes include:
- Class II: Less than 1 mW. Momentary exposure is unlikely to cause injury.
- Class IIIa: Less than 5 mW. Momentary exposure is unlikely to cause injury, but staring directly into the beam should be avoided. This is the most common class for laser pointers.
-
Regulations: The U.S. Food and Drug Administration (FDA) regulates laser products, including laser pointers. Lasers exceeding 5mW are generally not allowed to be marketed or sold as laser pointers.
-
Safety Precautions: Even low-power laser pointers can be harmful if misused. Here are some essential safety precautions:
- Never point a laser pointer at anyone's eyes.
- Do not shine a laser pointer at vehicles, especially airplanes. This is extremely dangerous and illegal.
- Keep laser pointers out of reach of children.
- Avoid prolonged exposure to the laser beam.
- Be aware of reflective surfaces. A reflected beam can still cause eye damage.
-
Higher Powered Lasers: Lasers exceeding 5mW are available but are generally not sold or marketed as "laser pointers" due to safety concerns and regulatory restrictions. These higher-powered lasers can pose a significant risk of eye damage and skin burns.
In summary, laser pointers, as legally defined and marketed, are generally low-powered devices with an output of less than 5 milliwatts to ensure relative safety with responsible use. Always adhere to safety precautions to prevent injury.
