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.
