Cleaning the lens and the SPI
Notice! Instrument damage/measurement error!
The lens is scratch- and moisture-sensitive.
If you touch the lens surface with your fingers, residues (e.g., grease) will
stick to the lens surface. These residues are hard to remove.
Check the lens for contamination.
When cleaning the lens, proceed as follows (if necessary):
1. Loosen the light channel sleeve
(1).
Fig. 22
2. Insert a clean ‘peek’ sample
needle or similar type of object
(1) through the opening in the
back panel of the SPI (2).
3. Carefully push the lens (3) out
and onto a piece of lens
cleaning paper.

4. Clean the contaminated lens using lens cleaning paper or a lint-free soft cloth.
5. Use a lint-free cloth to clean all other parts.
The lens and SPI are now clean.
