Causes of a defective image
In case of a defective image you should check the following:
-
Illumination is well done and luminous intensity is neither excessive nor too weak.
-
Eyepieces are well fit and objectives well screwed.

When cleaning the entire optical system you should proceed as follows:
o
Make the eyepieces turn checking the little specks are moving; if so you should clean
them. Make the head turn. You should never disassemble the head, but you can clean
it with delicacy by blowing the accessible surfaces of prisms with a plastic bulb.
o
the objective and, in case the parasite images also turn, clean it with the help of a dry
brush to remove the dust. Watch the front part of the microscope with a magnifying
glass or an inverted eyepiece.
-
Immersion oil is enough and does not contain air bubbles or impurities.
-
Thickness of slides, cover glasses and means of assembly is not too much as to avoid
focusing with medium or high magnification (there are standard sizes for both the slides
and cover glasses). Slides and cover glasses should be clean. Check that the slide is
properly located and there are not two cover glasses superimposed.

If the field of vision is cut:
Check the nosepiece is properly fit. To do that, turn it slightly back and forth until it fits.
If there is dust or dirt in the field of vision:
