Care of the unit

Cleaning optical surfaces

The multilayer T* (T-star) coating of our optical components (e.g. eye-

pieces, objective lenses) results in optimum image quality.

Image quality is impaired by even slight contamination of the optics or by

a fingerprint. In order to protect the internal optics from dust, the instru-

ment should never be left without the objective lens, binocular tube and

eyepieces installed when it is not in use. Always store objective lenses,

eyepieces and accessories which are not being used in dust-free cases.

The external surfaces of optical components (eyepieces, objective

lenses) should only be cleaned when required:

• Do not use any chemical cleaning agents.

• Blow off dust on the optical surfaces using a squeeze blower or re-

move the dust using a clean and grease-free brush.

Fogging of optical surfaces

To protect the eyepiece optics from fogging, we recommend using an

anti-fogging agent.

Note:

Anti-fogging agents provided by eyecare professionals for use with eye-

glass lenses are also suitable for Zeiss eyepieces.

• Please observe the instructions for use supplied with each anti-fog-

ging agent.

Anti-fogging agents do not only ensure fog-free optics. They also clean

the eyepiece optics and protect them against dirt, grease, dust, fluff and

fingerprints.

Cleaning mechanical surfaces

All mechanical surfaces of the equipment can be cleaned by wiping with

a moist cloth. Do not use any aggressive or abrasive cleaning agents.

Wipe off any residue with a mixture of 50% ethyl alcohol and 50% distilled

water plus a dash of household dish-washing liquid.
