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, eye-
pieces 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 aggressive or abrasive cleaning 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 mi-
croscope, we recommend the optics cleaning set available from ZEISS. For the
catalog number, please see the section "Device data".
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.
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.
