Care of the device
Cleaning
Cleaning the optical surfaces
The multilayer T* super anti-reflection coating of the optical components
(e.g. eyepieces, objective lenses) ensures optimum image quality.
Even slight contamination or a single fingerprint reduces image quality.
To protect the internal optics from dust, the system should never be left
without the objective lens, binocular tube and eyepieces. After use, cover
the device to protect it from dust. Always store additional objective lenses,
eyepieces, and accessories in dust-free cases when they are not being used.
Clean the outer surfaces of optical components (eyepieces, objective lenses)
only as required:
• Do not use any chemical agents.
• Remove dust from the optical surfaces using a squeeze blower or a clean,
grease-free brush.
For regular cleaning of the surgical microscope’s objective lenses and
eyepieces, we recommend using the optics cleaning kit available from ZEISS.
For the catalog number, please see the section “System data – Ordering data”.
Fogging of optical surfaces
To protect the eyepiece optics from fogging, we recommend using an anti-
fogging agent. Anti-fogging agents provided by eyecare professionals for use
with eyeglass lenses are also suitable for Zeiss eyepieces.
• Observe the Instructions for Use pertaining to the anti-fogging agent
concerned.
An anti-fogging agent does not ensure fog-free eyepiece optics. It cleans
eyepiece optics and protects them against dirt, grease, dust, lint,
and fingerprints.
Cleaning the mechanical surfaces
All of the system's mechanical surfaces can be wiped clean with a damp cloth.
Do not use any aggressive or abrasive cleaning agents.
Remove any residue using a mixture of 50% ethyl alcohol and 50% distilled
water plus a dash of household dish-washing liquid.
