Designated cover-glass thickness
Objectives are labeled with the supported cover
glass thickness. For instance, “
∞
/0.17” indicates that
a designated cover glass thickness of 0.17 mm.
■
Glass thickness of 0.17 mm:
When using the objective labeled “0.17”, use a cover
glass with a thickness of 0.17 mm. In this case, face
the cover glass downward, and set the specimen so
that the cover glass faces the objective.
■
Glass thickness of 1.2 mm:
When using the objective labeled “1.2”, use a
normal cover glass with a thickness of 1.2 mm. In
this case, face the cover glass upward, and set the
specimen so that the glass slide faces the objective.
