16 Cleaning
Due to its compact design, the device is characterized by almost maintenance-free operation.
When used for the intended purpose, it is possible that the device may need to be cleaned from time to time.
Very clean optical surfaces (cover glass) are required for the consistent and reproducible operation of the
device.
For cleaning, use a soft, lint-free cloth to clean the surface of the cover glass with a gentle pressure, without
scratching.
To clean stubborn dirt, commonly available window cleaning agent is recommended.
ATTENTION!
Ensure that no residues of the cleaning agent or scratches remain on the glass. These
can permanently damage the reproducibility of the results from the device.
ATTENTION!
As so many cleaning agents are available, we hope you understand that we cannot test
every single one. Resistance to cleaning agents and areas of use depends upon the
specific application.
Cleaning agents must be tested on an discreet area of the device under application
conditions to evaluate if they are suitable.
