Technique and Procedure

    Focusing with the Low Power Objective

   
Look through the oculars and adjust them for your interpupillary distance pushing them back and forth.


Then, start focusing by moving the specimen away from the objective by turning the coarse adjustment knob.

When the specimen comes into view, fine focus on one area of the specimen with the fine adjustment knob.

Close your left eye and make sure that the microscope is crisply focused for your right eye.


Now, open your left eye and close your right eye and focus the left ocular image by turning the diopter focusing ring on the left ocular.

Now adjust your microscope for optimal, Kohler illumination.
