WARNING
Damage to optics
Soiled optics absorb laser radiation and can thus be destroyed. Broken or damaged
lenses as well as thermal decomposition of lenses release particles which cause serious
damage to the health.
- The passive reflectors and optics in the area of the beam guidance should be
cleaned regularly.
- Special care is required when handling, attaching and cleaning these elements.
- Do not exert non-uniform pressure.
- Do not use tools or hard objects to clean the surface.
- Never touch the optics with your bare fingers.
- Never use cleaning tissues twice.
- When lenses get broken, damaged or thermal decomposed follow the protective
measures.
- Disposal according to regulations and laws valid in the users' country.
- Lenses with scratches or penetrations must not be used anymore!
2.8.4.1 Scratched or destroyed lens surface
Be aware that scratches in the coating may release small quantities of thorium, which may be harmful
upon inhalation or swallowing.
2.8.4.2 Thermal decomposition
Upon thermal decompositions, vapors of selenium oxide and zinc oxide are formed. Upon inhalation or
swallowing there is danger of poisoning.
Indicators for thermal decomposition of ZnSe include deposits in the form of red or white powder and
an unpleasant odor.
2.8.4.3 Broken lenses
When optical components of zinc selenide (ZnSe) are destroyed, toxic dusts and vapors are formed
which must not be inhaled. The dust can additionally cause irritations of the eyes, skin and respiratory
tract.
If a lens has been destroyed during operations, care is to be taken during removal and cleaning.
