HOW TO FOCUSE THE OBJECT (Fig. 9.1)
•
Bring object into rough focus.
•
Rotate fine focusing knob clockwise or anticlockwise to bring object into sharp focus.
•
If the object is outside the range of the fine focusing knob, bring the complete
microscope in the focus range by any of the following means:
a)
Roll the mobile stand forward and backward.
b)
Adjust the swivel arm towards left and right.
c)
Adjust the microscope angle left and right. For this loosen the head arm knob and rotate
the microscope.
A combination of the above steps will give you the true desired focusing median.
