Cleaning the Optical Filters
The optical filters used in the ZE5 Cell Analyzer lose performance when dirt, dust, or fingerprints are
present on the glass surface. Regularly inspect and clean these optical components to maintain high
system performance. See
filters.
Important:
These coated pieces of glass are delicate; handle them with care. Any scrape or
scratch on the surface could significantly affect the light passing though. When handling filters,
always wear gloves to avoid depositing oils and particles on the filter surface.
To clean an optical filter
1.
Remove the filter from the instrument.
2.
Gently spray compressed air on the surfaces of the filter to remove any large debris particles.
3.
Using a lint-free wipe (such as Kimwipes or camera lens paper) or swab moistened with isopropyl
alcohol, gently wipe the surfaces of the filter.
4.
Inspect the filter by holding it up to a light to ensure that all debris particles have been removed.
5.
Place the filter back into the instrument.
