Information about damaged optics

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 laser 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 user's country.
Lenses with scratches or lenses with penetrations must not be used anymore!
–
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.
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.
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.

Protective measures for damaged optics

Protective measures in case of thermal decomposition and scratched or broken lenses
For disposal use a protective mask or respiratory filter to prevent inhalation or ingestion of thorium.
•
Wash hands thoroughly aer contact with a scratched coating.
•
Protective measures in case of a broken lens
Upon perception of an unpleasant odor, switch off the machine.
•
Hold your breath.
•
Leave the area of the machine.
•
Before approaching the system again, wait for at least 30 min until the reaction has abated.
