Cleaning
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, we recommend the
optics cleaning set available from Carl Zeiss. For the catalog number, please
see the section "Device data".
Prevention of fogging
To keep the objective lenses from fogging, we recommend using an anti-fog-
ging agent. Anti-fogging agents provided by eyecare professionals for use
with eyeglass lenses are also suitable for Carl Zeiss objective lenses.
