place the specimen by sliding the specimen glass plate(s) on the
stage
3.
After positioning your specimen slides,(1 max) release the lever
handle.

Rotate the stage 360° to achieve best viewing position. The degree
of position can be noted.
“Vernier Scales”
These scales allow for easy identification of the specimen’s position
(coordinates), making it easy to return to a particular region of interest
after scanning the slide. (Figure 29.)
Cover glass
This is the glass plate placed on the specimen. For optimum optical
performance, the cover glass thickness, which is the distance from its
surface to the specimen surface, should be 0.17 mm.
Slide glass
This glass plate should ideally have a length of 76 mm, width of 26 mm
±1 mm and thickness between 0.9 and 1.4 mm.
