3.3.4 Condenser Adjustment
（
Fig.20
）
Turn the condenser focus knob to move the condenser up and down. Raise the condenser
when using the high magnification objective, and descend it when using the low magnification
one.
The condenser and the objective are coaxial. It has been adjusted well before leaving
factory, so the user needn’t to adjust them by self (the distance between the top of the
condenser and the stage should be in the range of 0.03mm~0.4mm.)
The highest position of the condenser has been adjusted too. It also needn’t any user’s
operation.
