9.10 Focus stop lever
The upper limit knob has two functions: prevent the
contact between slide and objective and acts as
"focus memory".
1. After focussing the specimen, pull the lever ①
toward the front of the microscope and lock it.
(Fig. 22).
• In this way the focus upper limit is set.
2. Now one can lower the stage with coarse focus
knob, replace the specimen and raise again the
stage up to the upper limit: specimen will be in
approximate focus and will need a fine adjustment
to get the proper focus..
• Fine focus movement is not affected by the
coarse focus lock.
• To unlock, move the lever in the opposite
direction to the one used for the locking.
• Two stoppers ② are inserted on the frame. DO
NOT REMOVE THE TWO STOPPERS.
9.11 Stage
Stage accepts standard slides 26 x 76 mm, thickness
1,2 mm with coverslide 0,17 mm. (Fig. 23)
It is possible to place two slides side by side on the
stage.
1. Open the spring arm of the slide holder ① and
place from the front the slide on the stage.
2. Gently release the spring arm of the slide holder.
• A sudden release of the spring arm could
cause the falling of the slide.
