What is the maximum output power for Class 3A lasers?

1 mW

3 mW

4 mW

Class 3A lasers are defined by their output power and the potential hazards they present. For Class 3A lasers, the maximum output power is specifically set at 5 mW or lower when measured in continuous wave operation, but when referring to specific instances, they are often characterized as up to 4.9 mW to ensure user safety guidelines are followed.

The correct answer, which indicates a maximum output power of 4 mW, aligns with these standards. This classification helps determine safety measures, as Class 3A lasers can present a risk of eye injury during direct exposure, but generally are considered less hazardous than the higher class lasers.

Understanding these classifications is essential for ensuring proper safety protocols and handling of laser devices in both public and workplace environments. This is why recognizing the specific output power for Class 3A lasers is critical for safety professionals and users alike.
