Pre-focusing Lever
}The pre-focusing lever ensures that the objective does not come in con-
tact with the specimen and simplifies focusing.
After focusing on the specimen with the coarse adjustment knob, turn
this lever @ in the direction of the arrow and lock; the upper limit of
coarse adjustment movement is set at the locked position.
After changing a specimen, refocusing is easily accomplished by rotat-
ing the coarse adjustment knob to reach the pre-focused position, then
making fine adjustments with the fine adjustment knob.
}Stage movement with the fine adjustment knob is not locked.
# If the pre-focusing lever is locked, the stage cannot be lowered to
the lower limit.

Selecting the Light Path

desired observation method.

# Be sure to slide the mirror selector lever until it contacts the stopper
position.
Effects of Dummy Slider
The dummy slider ² has been installed on the revolving nosepiece at
the factory. It can be replaced by loosening the clamping knob ³ when
a DIC prism is to be used. However, in observations other than DIC, be
sure to push in the dummy slider in order for prevention of flare.
