Viewing a Specimen
Your instrument is provided with a mechanical stage with a stage holder clamp and directional knobs –see figure 1b and 1c.
1. Use the clamp lever to open the clamping arm of the stage holder clamp (9).
2. Place a specimen slide (3" size) inside the holder and gently close the clamping arm against the slide.
3. Use the stage movement knobs (see Figure 1c) to position the specimen over the opening in the stage (4). The top
stage movement knob moves the X axis (forward and backward) whereas the bottom stage movement knob moves the
Y axis (side to side). Note: A vernier scale on both axes allows the exact marking and replication of an object in the
field of view that the user may want to come back to.
Figure 1b
Tip: To position the specimen directly under the objective lens, close the opening on the iris diaphragm (see Figure 1b)
until it is almost completely closed. You should see a small beam of light projected onto the specimen slide. Now simply
use the stage movement knobs (1c) to move the specimen directly inside the beam of light.
To achieve the best focus with your microscope, not only can you make adjustments with the coarse and fine focus knobs,
but you can also adjust the focus of each eyepiece (diopter adjustment (17) individually (your eyes are slightly different
from each other) as well as the interpupillary distance (distance between the center of your eyes). To achieve the sharpest
focus – see Figure 1d and:
