Focus Stop Lever; Stage - Optika B-1000 Series Instruction Manual

10.10 Focus stop lever

The upper limit knob has two functions: prevent the contact
between slide and objective and acts as "focus memory".
1. After focusing the specimen, pull the lever ① toward the
front of the microscope and lock it. (Fig. 28).
• 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.

10.11 Stage

Stage accepts standard slides 26 x 76 mm, thickness 1,2 mm
with coverslide 0,17 mm. (Fig. 29)
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 fall-
ing of the slide.
