Laser safety
4. Optical components (only for LS900 Edge machines)
Safety precautions
The various optics included in this machine contain ZnSe (zinc selenide).
When handling the optics, protective gloves should be worn.
•
Particular attention is required when handling, fixing and cleaning these elements.
•
Do not apply uneven pressure.
•
The entire optical system (mirrors and lenses) in the beam guiding zone must be cleaned regularly.
• Do not use hard objects or tools to clean the surface.
•
Never touch the optics with the bare hands.
•
Never use the same cleaning cloths more than once.
• Discontinue the use of lenses showing signs of scratching or impact.
Dirty optics absorb the laser radiation and can be destroyed as a result. Cracked or damages lenses release
particles which cause serious damage to health through inhalation or ingestion. This can cause irritation to the
eyes, skin and respiratory tracts.
For information on first aid measures and on handling scratched or cracked ZnSe lenses, refer to the
manufacturer's safety data sheets. By default, take the protective measures described in the paragraphs
below.
Protective measures in the event of thermal decomposition or scored or scratched lenses
Deposits in the form of red or white powder and an unpleasant smell indicate that thermal decomposition of the
ZnSe has occurred. Selenium oxide and zinc oxide vapours are formed. There is a risk of poisoning through
inhalation or ingestion.
1.
Remove the debris, using a safety mask or breathing filter to prevent inhalation or ingestion.
2. Wash the hands after any contact with the coating of a scratched lens.
