Laserklassificering

Laserklassificering refers to the process of categorizing lasers based on their potential hazard to human vision. This classification system is crucial for ensuring safety and implementing appropriate protective measures when working with or around laser devices. The primary international standard for laser classification is IEC 60825-1, which divides lasers into several classes, with higher numbers indicating greater potential hazard.

Class 1 lasers are considered safe under normal operating conditions. Class 1M lasers are safe for viewing with optical instruments but can be hazardous if viewed directly. Class 2 lasers are visible-light lasers where eye protection is typically achieved through the natural aversion response of blinking. Class 2M lasers are similar to Class 2 but can be hazardous if viewed with optical instruments.

Class 3R lasers present a moderate risk, and protective eyewear is often recommended. Class 3B lasers pose a significant risk to the eye, and direct viewing is dangerous. Class 4 lasers are the most hazardous, capable of causing severe eye and skin damage, and even fire. These lasers require strict safety protocols, including enclosed beam paths and mandatory protective eyewear.

The classification is determined by factors such as the laser's wavelength, power output, and beam characteristics. Manufacturers are responsible for correctly classifying their laser products and providing appropriate warning labels and safety information to users. Understanding laser classification is essential for anyone who operates, maintains, or is exposed to laser light.
