Components requiring maintenance
5.6.1 View port
Due to the image quality when the high magnification stereo microscope (230x) is
used the instrument is delivered with a viewing port consisting of an optical grade
window without protective glass which would influence the image quality. However,
when a low magnification stereo microscope (< 77x) is used a protective glass
(optional) can be inserted with less effect to the image quality due to the reduced
magnification.
Cleaning or replacing the protective glass
Assembly
Protective glass (optional)
The protective glass should be cleaned with acetone or a fine polishing paste with
grain size < 1 µm. The protective glass must be removed from the cover flange for
cleaning.
