Adjusting the Diopter
The diopter adjustment ring on an eyepiece can be adjusted to match the eyesight of your right and left eyes.
A properly adjusted diopter compensates for differences in visual acuity between the right and left eyes of a person,
making binocular observation easier. It also minimizes focal deviations when switching magnification, optimizing the
performance of the objective.
Adjust the diopter settings for both eyepieces.
Notch on eyepiece
The eyepiece has a notch to prevent rotation. When attaching, match the notch with the protrusion on the eyepiece
sleeve. Otherwise, eyepiece is not attached to the correct position.
(1)
Turn the diopter adjustment ring on the right and left
eyepieces to align the end face of the diopter adjustment ring
with the line. (This is the diopter adjustment reference
position.)
(2)
Follow Steps 1 through 9 in Chapter 1 "1.2 Bright-field
Microscopy Procedure" to focus on the specimen using the
10x objective.
(3)
Press the nosepiece forward/reverse rotation buttons on the
main body, or the nosepiece address button on the remote
control pad to bring the 40x objective into the optical path.
Adjust the focus onto the specimen by turning the coarse
focus knob and then the fine focus knob.
(4)
Bring the 10x (or 4x) objective into the optical path.
(5)
While looking into the left eyepiece with your left eye without
touching the focus knob, focus on the specimen by turning
the left diopter adjustment ring.
(6)
While looking into the right eyepiece with your right eye
without touching the focus knob, focus on the specimen by
turning the right diopter adjustment ring.
(7)
Repeat Steps (3) through (6) to make sure the focus has
been adjusted properly.
