Cleaning the Camera Optics (Continued)
Verifying the Location of Dust or Dirt
Avoid needless cleaning of the DMC 2 camera optics by determining the location of
dust or dirt before proceeding. You can determine whether the dust or dirt is in the
camera optics or the microscope optics by comparing two images as follows:
1
Take a picture with the camera in its normal position.
2 Rotate the camera 30 or 40 degrees, and take a second picture of the same speci-
men.
If the spot moves in relation to other elements in the picture, it is caused by dust
on the camera anti-aliasing filter or the c-mount adapter lens. In this case, skip to
step 3 to determine the location.
If the dust remains in the same location relative to other elements in the picture, it
is caused by dust on the microscope optics. Discontinue this procedure and refer
to the cleaning instructions provided with your microscope.
