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.
(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 10 in Chapter 2 "3 IR-DIC (Infrared
Ray Differential Interference Contrast) Microscopy
Procedure" to focus on the specimen using the 10x
objective.
(3) Bring the 40x objective into the optical path, and turn the
coarse focus knob and then the fine focus knob to focus on
the sample.
(4) Bring the 10x (or 4x) objective into the optical path.
(5) Look into the right eyepiece with your right eye without
operating the focus knob, and then focus on the sample by
turning the right diopter adjustment ring.
(6) Look into the left eyepiece with your left eye. Without
operating the focus knob, focus on sample by turning the left
diopter adjustment ring.
(7) Repeat Steps (3) through (6) to make sure the focus has
been adjusted properly.
