What is the maximum continuous wave power for a Class 3B laser?

The classification of lasers is based on their potential to cause harm, with Class 3B being defined as lasers that can produce hazardous exposure levels. A Class 3B laser presents a risk of eye injury with direct viewing and can also cause burns to the skin, depending on the exposure duration and conditions.

The maximum continuous wave (CW) power for a Class 3B laser is indeed 500 milliwatts (mW). This means that lasers operating at power levels up to 500 mW will fall into this category, which highlights the importance of proper safety measures when dealing with such equipment. Understanding the safety classifications is crucial for Laser Safety Officers to evaluate risks associated with laser use in various environments, ensuring appropriate protective measures are in place to mitigate potential dangers.

The other power levels listed do not classify as Class 3B, as they either fall below the threshold or belong to different classes, indicating less or more potential for harm in terms of laser exposure.
