Special hazards caused by mirrors made of beryllium

Beryllium mirrors can be destroyed by improper loading. This can lead to a release of berylli-
um dusts. These dusts can cause cancer, are toxic if swallowed and very toxic by inhalation.
Please observe the specified maximum applicable laser power in the data sheet.
Please note also, that soiled mirrors strengthen the absorption of laser power and thereby
increase the risk of destruction of the mirror.

Special hazards caused by lenses made of zinc selenide

Zinc selenide lenses can be destroyed by improper loading.This can lead to release of dust
with hydrogen selenide and selenium dioxide. These dusts can cause cancer, are toxic if
swallowed and very toxic by inhalation.
Please observe the specified maximum applicable laser power in the data sheet.
Please note also, that soiled lenses strengthen the absorption of laser power and thereby
increase the risk of destruction of the lens.
Therefore it is essential to ensure suitable suction in the production environment. In addition,
the outer protective glass of the F-Theta lens must be checked for dirt regularly and cleaned if
necessary. For non-removable deposits and after wear, which is caused by frequent cleaning,
the protective glass of the F-theta lens should be replaced.
