What is a class 3B laser?
The class 3B (IIIB) laser pointer is a medium-to-high power laser. The output power is usually between 5 and 500 milliwatts. It's more hazardous than class 3A lasers, and if used improperly, this type of laser beam can cause damage to the eyes and skin. For long-term use, we recommend that you wear safety goggles.
Class IIIB lasers are usually used in astronomy, medical treatment, laser experiments, outdoor adventures, and other related fields. Before purchasing, you can contact us to choose the most suitable class 3B laser for you.
