Warning
Zinc selenide lens, telescope and laser exit window.
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.
– 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 (wear cloves).
– 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 penetrations must not be used anymore.
