Did you know – Lasers classification

For safety reasons, Lasers are classified depending on their potential risk of injuries to humans’ eye and skin.

By law, all lasers products must have a label mentioning the class level. This number can be written either in Arabic numeral or in Roman numeral.

In the case of European law, lasers are classified over 7 categories: 1, 1M, 2, 2M, 3R, 3B, 4. The danger increases with the number. The classification is done regarding the wavelength (i.e the color), the power and the emission mode (pulsed or continuous) of the laser product.
