Maintenance

8.3 Cleaning the Lens

Care should be taken to keep the lens clean. Any foreign matter on the lens will affect the accuracy of
the measurements. Be sure to take care when cleaning the lens. Please observe the following:
1. Blow off lose particles with clean air.
2. Gently brush off remaining particles with a soft camel hair brush.
3. To remove any more severe contamination use a clean, soft cloth dampened with distilled
water. In any case, do not scratch the lens surface!
For finger prints or other grease, use any of the following:

Denaturated alcohol

Ethanol

Kodak lens cleaner
Apply any of the above to the lens. Wipe gently with a clean, soft cloth until you see colors on the lens
surface, then allow to air dry. Never wipe the surface dry, this may scratch the surface. If the lens is
contaminated with silicones (e.g. from hand creams), clean it carefully using Hexane. Allow the lens to
air dry.
Do not use any ammonia or any cleaners containing ammonia to clean the lens.
This may result in permanent damage to the lens' surface!

8.4 Replacing a Protective Window

8.4.1 Models produced after May 1999

Attention! Beginning production date May 1999, the models contain a thread allowing an easier
protective window exchange. (If you received your model together with this manual, your model was
produced after May 1999.) If you own an older model, refer to the description given in section 8.4.2
Models produced before May 1999
Make sure to use the appropriate protective window for the spectral range of your sensor model, for
more information see section 6.10
The window material is placed in a metal ring with a thread with an inner rubber gasket. This rubber
gasket hermetically seals the sensor against atmospheric contaminants.
Replace the protective window using the special tool supplied with the spare window. Put the tools
nozzles into the wholes on the window's mounting ring. Now gently unscrew the protective window
from its mount by turning to the left. Take care to screw in the new protective window as tight as
possible, but do not over tighten!
