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.

Optical Safety

Any dust on the end of the collimator assembly can burn the lens and damage the laser.

CAUTION: If the output of the device is delivered through a lens withan anti-reflection coating, make sure that the lens is of good quality and clean.

(1) Make sure your product is grounded through the PE line of the AC power cord. The
grounding must be firm and reliable

WARNING: Any interruption from the protective earth will electrify the enclosure, which may result in personal injury.

CAUTION: Failure to connect the correct voltage could damage the product.
