What class laser is in a CD player?
Class 1 lasers are low powered devices that are considered safe from all potential hazards. Some examples of Class 1 laser use are: laser printers, CD players, DVD devices, geological survey equipment and laboratory analytical equipment.
Can a Class 2 laser burn stuff?
A Class 2 laser is relatively weak. It normally would not harm an eye unless a person deliberately stared into the beam. Laser protective eyewear is normally not necessary. A Class 2 laser is not a skin or materials burn hazard.
What is a Class 2 laser?
Class 2 lasers are low power lasers that emit visible radiation and do not exceed a power output of 1 mW. For this laser class, the normal human aversion response of (0.25 second) to bright radiant sources affords eye protection if the beam is viewed directly.
What happens if you look into a class 2 laser?
A class 2 is “safer” than a class 3. Many laser pointers are in the range of 1 to 5 milliwatts (mW), a subclass of 3 called 3A. A close reading of exposure limits indicate that a 5 mW laser could cause eye damage. If it gets into the eye, you receive all the laser’s energy, not just a fraction.
Are Class 2 lasers safe?
A Class 2 laser is considered to be safe because the blink reflex (glare aversion response to bright lights) will limit the exposure to no more than 0.25 seconds. It only applies to visible-light lasers (400–700 nm). Intentional suppression of the blink reflex could lead to eye injury.
Do Class 2 lasers require labels?
These labels are intended to be permanently affixed to Class 2 lasers that are not likely to be used outdoors or otherwise aimed at aircraft. They do not contain the warning about aiming at aircraft. If the Class 2 laser product is large enough, it is preferred to use the full-size Laser Safety Facts label above.
What is a Class 1 laser device?
A class 1 laser product is a device that complies with laser safety standards from the International Electrotechnical Commission (IEC). These regulations ensure that lasers identified with a “Class 1 laser product” label are safe. As such, they do not require any additional laser beam control measures.
