Features of American-made laser pointers
According to the regulations in 21CFR Part 1040.11(b) of the US FDA Center for Equipment and Radiological Health (CDRH), laser pointers manufactured in the United States are measurement, leveling, and calibration (SLA) laser products. The CDRH laser class restrictions for SLA laser products, including Laser pointer, belong to class IIIa. CDRH also recognizes IEC 60825-1 Level 3R, which is equivalent to CDRH Level IIIa. These CDRH and IEC 60825-1 laser levels are equivalent to laser power no more than 5mW. Laser power exceeding 5mW is very dangerous and may cause potential hazards, such as temporary vision problems or eye damage. Therefore, any laser pointer that emits radiation exceeding Class IIIa/3R shall not be imported into the United States, or sold or promoted in the United States.

The United States, Japan and China provide comprehensive laser testing laboratories that can test all types of US-made laser pointers in accordance with the laser safety requirements of CDRH and IEC. The services that can be provided include laser pointer safety testing to complete laser testing services. After the test is completed, laser products are exported to the United States for FDA requirements. Lasers are divided into the following five types according to the emission frequency: class I, class II, and class III a , Class III b, class IV, generally can only do two kinds of class I and class II, these two are classified as low-risk, and the inspection is not strict, just provide the materials for registration.
