8.1.1 Cleaning optical surfaces
The multi-layer T* coating of the optical components (e.g. eyepieces, objective lenses) ensures optimum
image quality.
Image quality is impaired by even slight contamination of the optics or by a fingerprint. 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 system to protect it from dust. Always store objective lenses,
eyepieces and accessories in dust-free cases when they are not being used.
Clean the exterior surfaces of the optical components (eyepieces, objective lenses) only when
necessary:
 Do not use any chemical agents.
 Remove dust from the optical surfaces using a squeeze blower or a clean, grease-free brush.
For the regular cleaning of objective lenses and eyepieces of the surgical microscope, we recommend
the optics cleaning set available from ZEISS.
8.1.2 Prevention of fogging
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.
Please observe the Instructions for Use supplied with each anti-fogging agent.
Anti-fogging agents do not only ensure fog-free eyepiece optics. They also clean the eyepiece optics
and protect them from dirt, grease, dust, fluff and fingerprints.
8.1.3 Cleaning mechanical surfaces
All mechanical surfaces of the system can be cleaned by wiping them with a damp cloth. Do not use
any aggressive or abrasive cleaning agents.
Clean off any residue using a mixture of 50 % ethyl alcohol and 50 % distilled water plus a dash of
household dish-washing liquid.
