Diopter adjustment
•
Diopter adjustment compensates for differences in vision between the left and right eyes. In addition to
making observation through both eyes easier, this adjustment also reduces the
extent to which focusing is lost when the objective magnification is changed. In particular,
this occurs when a low power objective is used.
•
Before adjusting the diopter, bring a specimen into focus using the 10x objective.
•
Turn the diopter compensation ring on each eyepiece until the adjustment ring is adjusted to
“0” position.
•
Position 40x objective into the optical path and bring the specimen image into focus by turning
the coarse and fine focus knobs.
•
Position either 4x or 10x objective into optical path. Without adjusting the fine and coarse focus knobs,
turn the diopter rings on the eyepieces so that the specimen images in the left and right eyepieces are
focused individually.
•
Repeat the above step twice.
