Class 1 lasers are characterized by what feature?

Class 1 lasers are categorized by their output power, which is inherently low enough to prevent eye injury under normal operating conditions. More specifically, the output power of Class 1 lasers is always below the threshold that would cause damage to the human eye, making them safe for use in a variety of environments without the need for special safety precautions.

This feature is fundamental to the classification of lasers, as it ensures that users can operate these devices without the risk of harm from exposure, even in cases where the laser is viewed directly. Class 1 lasers include many common applications, such as those found in laser printers and CD players, which operate safely due to their low power output.

Understanding this classification is essential for safety professionals, as it influences the handling, usage, and regulatory considerations associated with different types of lasers.
