3-4 Placing Specimens
1. Fix the specimen ② onto the sample slide ① using
modelling clay or plasticine ③; make sure that the specimen
surface is parallel to the sample slide. It may be necessary to
use a levelling press to flatten the specimen (Fig. 19)
2. Place the slide on the mechanical stage. Use the stage clips to
gently clamp the slide.
3. Move the specimen into position by using the horizontal and
vertical adjustment controls of the mechanical ruler.

Caution – When changing the objective; be aware of
your working distance and do not allow the
objective to touch the specimen. This could cause
damage to the lens.
3-5 Adjusting the Interpupillary Distance
The interpupillary distance range between: 48mm ～75mm. Make
sure when you are viewing a subject that the left and right fields of
view coincide with each other. To adjust the FOV (field of view) use
the left and right prism barrels. See Fig. 28 to clarify.
3-6 Adjusting the Dioptre
After you have achieved focus with the right ocular, but your left
ocular is out of vision, this can be adjusted by turning the left
dioptre ring (Fig.21), as the right ocular tube is fixed. This should
achieve a comfortable focus for both eyes.
