Cleaning optical surfaces
The multilayer T* super anti-reflection coating on 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 finger-
print. To protect the internal optics from dust, the system should never be left
without the objective lens, binocular tube, and eyepieces. Cover the device
after use 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 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 “Device data – Ordering data”.
Fogging of optical surfaces
We recommend using an anti-fogging agent to protect the eyepiece optics
from fogging. 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.
An anti-fogging agent does not ensure fog-free eyepiece optics. It cleans
eyepiece optics and protects them against dirt, grease, dust, lint, and finger-
prints.
Cleaning 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.
Clean off any residue using a mixture of 50 % ethyl alcohol and 50 % distilled
water plus a dash of household dish-washing liquid.
