Laser Safety

The laser pointers are uesd for consumer market, like general office working tool or teaching tool in class.

The laser modules are critical components for industrial/technical applications. They are mounted inside machine and could emit more precise laser beam, ideal for industrial applications. Therefore, Quarton's laser module is the preference if you need to customize the unique specifications or work for high quality.

Class IIIb hand-held lasers are too dangerous for use as pointers or amusement articles. Furthermore, promotion of Class IIIb or IEC Class 3B products for pointing or amusement violates FDA requirements and United States law. Manufacturers of such products may be required to repair, replace, or refund the purchase price of violative products distributed in the U.S. These products are also subject to detention and seizure by the U.S. Customs and Border Protection when imported.

Irresponsible use of more powerful laser pointers poses a significant risk of injury to the people exposed. Persons who misuse or irresponsibly use lasers are open to personal liability and prosecution.


According to FDA requirements:

POLICY: In keeping with this recognition of a hazard and the advice given, the Center for Devices and Radiological Health (CDRH) will object to any intentional exposure of the public to hazardous levels (1.e., greater than Class I levels) of laser or collateral radiation (light) from this type of equipment. Further, the CDRH will object to any instructions or promotion of Class II or IIIa demonstration laser products (projectors, scanners, shows, etc.) that do not adequately warn the user to prevent such exposure.

Class I audience exposure levels.
Only Class I levels of laser radiation have no known hazard and these are the only exposure levels that are considered safe for direct exposure of people. Exposure of the audience to levels in excess of the Class I limits is not to be promoted or encouraged in any way.

Class II warning:
CAUTION Laser Radiation (or Light)
Do Not Stare Into Beam

Class IIIa warning: DANGER Laser Radiation (or Light)
Avoid Direct Eye Exposure

These levels are hazardous to the eyes. No direct or reflected beams may be directed into audience areas or used to scan the audience in any way. A projector certified as Class II or IIIa cannot be used for audience scanning unless the projector is equipped with an adequate scanning safeguard which will prevent scanning above the Class I limits and adequate user instructions for achieving the Class I levels are provided.

Class IIIa or IEC Class 3R lasers can be dangerous. Class IIIa lasers can cause temporary visual effects such as flash blinding, which could distract or startle the person exposed. The risk of injury is very small when Class IIIa pointers are used responsibly because natural body motion of a person holding the pointer or motion of a person who might be exposed makes it difficult to expose the eyes for a long period of time. People also have a natural aversion to bright lights and are likely to close their eyes and turn their heads if exposed.
