7.1.4 Cleaning the deflector mirror
In system setups with deflector mirror, we suggest the following cleaning:
• The external deflector mirror is a front surface mirror. That means that cleaning it
affects the optical effective area itself.
• Only touch the reflector surface if absolutely necessary, and then only partially, if
possible.
WARNING!
DAMAGE TO THE OPTICAL EFFECTIVE AREA OF THE DEFLECTOR MIRROR
Using the wrong cleaning technique or aggressive cleaning agents can damage the
deflector mirror, thus impairing the reading performance of the camera system.
▸
That is why you should not clean the deflector mirror unless it is necessary.
▸
Only touch the reflective surface when this is absolutely necessary (e.g., if it is very
contaminated).
▸
Never touch the entire reflective surface.
▸
Do not use oily compressed air from a can.
▸
Do not wipe the mirror with a towel as this could cause irreversible scratches.
▸
Carefully blow away dust and loose dirt particles with clean, oil-free air.
▸
Carefully remove any solid particles using a camel-hair brush previously degreased
with acetone. Do not apply any acetone directly to the mirror surface.
The camel-hair brush must have the following properties:
• Camel-hair brush for photographic purposes.
• Natural hair to prevent static charge.
• Suitability for cleaning optical surfaces, lenses, negatives.
▸
Fill a clean plastic spray bottle with distilled water.
▸
Spray the mirror surface uniformly with distilled water. Hold the mirror at an angle so
the distilled water can drip off.
▸
Let the mirror dry. Do not wipe the mirror dry!
▸
Spray the affected areas with a household glass cleaner.
▸
Carefully wipe paper tissue (recommendation: “Kleenex”) over the affected area.
Only apply light pressure to the mirror. Do not scour!
▸
Let the mirror dry. Do not wipe the mirror dry!
