What is the recommended distance for safe viewing of Class 3B lasers?

The recommended distance for safe viewing of Class 3B lasers is at least 10 meters. Class 3B lasers are considered hazardous to the eye; direct exposure can cause injury. Maintaining a distance of at least 10 meters reduces the likelihood of eye exposure to reflective surfaces or direct beams.

The rationale behind this distance is based on the increased intensity and potential for eye damage associated with Class 3B lasers, as they can produce significantly higher power and more concentrated beams than lower classes. Therefore, establishing a safe distance helps to minimize the risk of accidental exposure to the laser beam.

In professional settings where Class 3B lasers are used, implementing appropriate safety protocols, such as controlled access zones and protective barriers, helps ensure that individuals remain at a safe distance from the potentially harmful effects of the laser beams. This is also supported by safety standards and guidelines that outline minimum distance requirements for safe operation and viewing conditions.
