4.3.2 Iris aperture adjustment
Stir the handle of iris aperture of condenser to
adjust size of iris aperture for adjusting the
contrast of the specimen.
4.4 Interpupillary distance and diopter
adjustment (Shown in Fig.5)
4.4.1 Interpupillar distance is different for everyone, so interpupillary distance
should be adjusted before using binocular microscope. Please take the two
eyepiece tubes to turn until the bright rings observed by two eyes are in
superposition entirely.
▲B100 monocular microscope don't need to be adjusted.
4.4.2 Diopter adjustment
As focusing for binocular, user should observe right eyepiece with right eye, and
make the right eyepiece clear by focusing adjustment, then observe the left
eyepiece, at the same time, adjust the diopter ring of the left eyepiece tube to
make the image of left eyepiece clear as same as the right eyepiece.
4.5 Focusing adjustment
Usually 10X objective should be used for focusing adjustment first. Take 10X
objective into bright path, then observe the specimen with right eyepiece by
right eye and turn coarse focusing knob to find the image, then turn slowly fine
focusing knob to make the image clear.
All objectives of our microscope are precisely adjusted, and approximate clear
image should be found with the other objectives after getting the clear image
