Hazards due to damaged optics

Warning
Damage to the lenses.
Dirty lenses absorb laser radiation, which can destroy them. Broken or damaged lenses and thermal
decomposition of lenses release particles that are hazardous to health.
–
Clean the deflection mirror and lenses in the laser beam guidance area regularly.
–
Take particular care when handling, attaching and cleaning.
– Always apply even pressure to the lens and do not apply pressure to one side only.
– Do not use tools or hard objects to clean the surface.
– Do not touch the lens surface with your fingers.
–
Only use cleaning cloths once, never repeatedly.
–
In the event of broken or damaged lenses or thermal decomposition of lenses, follow the appropriate
protective measures (see the following chapter).
– Disposal must be in accordance with local laws.
– Scratched lenses or lenses with a burn mark must not be used!
SCRATCHED OR DAMAGED LENS SURFACE
Please note that scratches in the surface coating may produce small amounts of toxic emissions that are hazardous to
health if inhaled or swallowed.
THERMAL DECOMPOSITION
Thermal decomposition produces smoke from selenium and zinc oxides. There is a risk of poisoning if inhaled or
swallowed. Indicators of thermal decomposition of ZnSe (zinc selenide) are deposits in the form of white or red powder
and an unpleasant odor.
BROKEN LENSES
When optical components made of ZnSe (zinc selenide) are destroyed, toxic dust and vapors are produced, which must
not be inhaled. The dust can also cause irritation to the eyes, skin and respiratory system. If a lens is destroyed during
operation, extra care must be taken when removing and cleaning it.

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.
