9.10 Centering 1X objective (ST-50LED)
•
This procedure may be required if you want to use the 1X
objective on the ST-50LED stereomicroscope.
It may happen that once the 1x objective is mounted on the
microscope, the images that are observed in the two eyepieces
are not perfectly aligned and one of the two images is shifted.
(Fig. 12)
1. Remove the two silver screws from the 1x objective lens
body. (Fig. 13)
2. Remove the plastic cover of the objective lens.
3. Place a sheet of paper under the microscope and focus on
a recognizable detail within the paper, looking through the
right eyepiece.
4. Now observe in the left eyepiece and, using three Allen
wrenches, tighten or unscrew the three screws that hold the
left lens in place.
This operation ensures that the image observed in the left
•
eyepiece is consistent with the image observed in the right
eyepiece (i.e., that there is no obvious mismatch between
the images observed at the two eyepieces).
5. The final result of the centering operation should be
something similar to what is shown in Fig. 15.
6. Once the centering operation is complete, replace the plastic
lens cover and reinstall the silver screws. (Fig. 13)
