Cleaning the Field Lens
If the mirror shutter is in front of the imager,
•
briefly press the PHASE button. The shutter
is positioned to protect the mirror surface
from damage as far as possible.
Before cleaning the field lens, switch the
•
camera’s main switch off and disconnect
the camera from the power supply!
Remove the lens or the protective cap.
•
Do not touch the sensor or the mirror surface!
•
Using the
•
special forceps (Hirschmann clamp)
from the camera’s toolkit, pull the ground
glass out of the holder by its tongue.
Using the
•
special forceps, first lift the field lens
upwards by its tongue then pull it out of its holder.
Clean the field lens with a dry, lint-free cloth.
•
Check that ground glass and field lens to
•
be inserted are completely clean.
Using the
•
special forceps, push the field lens into the
holder as far as it will go. The red marker point must be
