Window Maintenance
The windows of the vision system and laser must be kept clean and free of defects to
ensure proper operation. Any scratches, dust or dirt will impact the accuracy of
acquired images.
CAUTION
:
Use care not to damage the anti-reflective coating on the
windows.
Cognex makes the following recommendations for cleaning the laser and vision
system windows:
l
Unplug the unit so the laser cannot be enabled.
l
Use lint-free tissue or an optical grade cotton swab ("Q-tip").
l
Use reagent-grade isopropyl alcohol.
l
Use minimal pressure.
l
l
Use several tissues or swabs.
l
Start at the center of each window and spiral out to the edges.
l
Rotate the tissue or swab during cleaning so dirt is not dragged across the
surface.
