Laser Classification


This series of lasers are classified as a high power Class 4 laser instrument according to the European Community

standards EN 60825-1, clause 9.This product emits invisible laser radiation at or around a wavelength of 1080 nm,

and the total light power radiated from the optical output is greater than 100W~2000W (depending on model).

Direct or indirect exposure of this level of light intensity may cause damage to the eyes or skin. Despite the radiation

being invisible, the beam may cause irreversible damage to the retina and/or cornea. Appropriate and approved

laser safety eyewear must be worn all the time while the laser is operating



WARNING: You must use appropriate laser safety eyewear when this device is operating. The laser

safety eyewear is selected according to the range of wavelengths emitted from this product. The end

user must ensure that the laser safety eyewear being used protects against light emitted by the

device over its entire range of wavelengths. Please verify that the personal protective equipment

(e.g. enclosures, viewing windows or viewports, eyewear, etc.) being utilized is adequate for the

output powerand wavelength ranges listed on the product.
