Laser Radiation IEC/EN 60825 Testing

Laser Radiation Levels

Laser radiation primarily poses a risk to human eyes and skin, depending on the angle α, wavelength, photochemical hazard power, photothermal hazard power, and laser/LED hazard classification. China JJR Laboratory provides testing services.

Class 1 Laser

Low risk, safe under reasonably foreseeable conditions of use, including optical instruments used for beam observation.

Class 1M Laser

Wavelength between 302.5nm and 4000nm, safe unless used with optical auxiliary devices (e.g., binoculars).

Class 2 Laser

Wavelength between 400nm and 700nm, contact radiation should not exceed Class 2 AEL (accessible emission limits), and any emission outside this wavelength range must be below Class 1 AEL.

Class 2M Laser

Wavelength between 400nm and 700nm, potential danger when observed with optical instruments, and any radiation outside this wavelength range must be below Class 1M AFI.

Class 3R Laser

Wavelength range between 302.5nm and 1060nm, potential danger but lower risk compared to Class 3B lasers. For wavelengths between 400nm and 700nm, the radiation limit is within 5 times the Class 2 AEL, and for wavelengths outside this range, within 5 times the Class 1 AEL.

Class 3B Laser

Generally dangerous under direct beam observation but safe when observing diffuse reflection.

Class 4 Laser

Dangerous under both beam and diffuse reflection observation conditions. Can cause skin injury and is a potential fire hazard.
