ð Never touch the quartz-block end-face or the glass surface of the
screwable protective sleeve with your fingers.
Use of compressed air
ð Never use compressed air in the immediate
vicinity of the fiber connector, since this may
lead to contamination of the quartz-block end-
face.
Required materi-
als
You need the following materials for the cleaning:
• Lint-free cleaning swabs
• Isopropanol (anhydrous)
• Acetone (anhydrous)
• Compressed air (oil-free, anhydrous)
• Microscope, model IPG or similar
• Light-source
The cleaning swabs are included in the scope of delivery. The micro-
scope and compressed air are included with the order.
Preparation
1. Ensure a clean working place close to the process optics. Then
minimize the risk of a re-contamination of the fiber connector af-
ter the cleaning process.
2. Keep a clean protective cap available for the process optics.
3. Remove any impurities within the protective cap with com-
pressed air as a precaution before use.
4. After cleaning, place the protective cap on a clean storage surface
with the open side down.
5. Place the microscope on a level surface to ensure a secure base of
the microscope.
6. Use a damp cloth to remove coarse dirt from the fiber connector
and the optics near the fiber connector.
7. Alternatively, you can remove the coarse dirt with compressed
air. After compressed air usage, wait a while until any dispersed
dust has settled before you disconnect the fiber connector from
the optics.
8. Disconnect the fiber connector from the optics (see the following
figure). To unlock the bayonet mount, turn the grooved handle
counterclockwise until the stop (1). Pull the fiber connector care-
fully off (2).
