Class 3B Laser

Definition

A Class 3B laser is a type of laser that can emit radiation with power between 5 and 500 milliwatts. These lasers are considered hazardous to the eyes and skin when viewed directly, making safety precautions critical in their use. Class 3B lasers are commonly utilized in various applications such as scientific research, industrial processes, and medical treatments due to their ability to deliver focused energy for precise tasks.

5 Must Know Facts For Your Next Test

1. Class 3B lasers can cause eye damage if viewed directly, even momentarily, making protective eyewear essential during their operation.
2. These lasers are frequently used in applications like laser pointers, barcode scanners, and certain surgical procedures where precision is crucial.
3. Unlike Class 4 lasers, Class 3B lasers do not produce significant diffuse reflections, meaning they pose less risk of harm from scattered light.
4. In research settings, Class 3B lasers can be used for experiments that require specific wavelengths for spectroscopy and imaging techniques.
5. Regulations for Class 3B laser use often include requirements for controlled access to laser areas and proper signage to warn of potential hazards.
