3.6.3 Adjusting
Interpupillary
Distance
Adjust the distance between the objectives to match
the distance between the eyes of the observer. This
adjustment makes it easier to perform observation
with both eyes.
Operation:
Binocular part
Distance between
eyepieces
Widen the binocular part.
The distance between the
eyepieces increases.
Narrow the binocular part.
The distance between the
eyepieces decreases.
Adjusting the interpupillary distance
Pupillary distance adjustment
After the diopter adjustment for the eyepieces is complete, place the 10x objective into the optical path,
focus on the specimen, and then while looking through the eyepieces with both eyes, adjust the pupillary
distance of the binocular part until both fields of view form a single circle.
Use of pupillary distance graduations
The binocular part has pupillary distance graduations
Remembering the pupillary distance is helpful so that pupillary distance can be easily adjusted the next
time.
3.6.4 Operating
the Centering Telescope
The centering telescope is an optical instrument that
is mounted on the binocular part to observe the pupil
plane of the objective.
The centering telescope is used for different
purposes, such as adjusting the aperture diaphragm,
checking for air bubbles during oil-immersion
microscopy, adjusting the azimuth of the polarizer,
and adjusting the position of the phase ring for Ph
microscopy.
To use the centering telescope, remove one of the
eyepieces from the binocular part and attach the
centering telescope. The focusing position can be
adjusted by turning the eyepiece section while
holding the flange section on the centering
telescope.
Operation:
Centering telescope
Focusing position
While holding the flange
section, turn the eyepiece
section.
The focusing position of
the centering telescope
moves.
