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 with 10X
objective. If the image isn’t enough clear with the other objectives, please turn fine
focusing knob slightly to find the satisfactory image.
▲
Don’t turn left and right coarse and fine focusing knobs with different direction with
power at the same time, if so, the focusing system will be damaged.
▲
Don’t directly pull objective to turn nosepiece when user changes the different
objectives, if so, optical quality of
microscope possibly be affected. The
right way is to take the tooth-like part
of the nosepiece to turn it, and make
the objective into correct position and
into the bright path.

ring (Shown in Fig.6)

unit to prevent the stage from sliding down automatically and to improve the comfort
