screws, bring this point in
the center of the field of view.

coincides with the system's
optical axis. (Fig.28)

tating the nosepiece. Repeat
the above operation (stage
rotations), and bring the point
into the center using the
objective centering screws
(not the stage centering
screws). (Fig.29)
NOTE :The stage can be
locked in its position using the
stage lock knob.

view of your sample, you can

aligned along Z axis by rota-
ting this disc. (Fig.30)
The lens can also be centered
in X-Y axis by means of two
screws located at the back of
the lens. (Fig.31)
