Cover Glass
I
An Olympus objective engraved "160/0.17"
requires a cover glass of 0.17mm thickness.
If the numerical aperture of the objective is 0.7 or higher (except immersion objectives) and
no correction collar is provided, the resolving power deteriorates to a great extent if cover
glass thickness deviates from the above listed value.
IVOTE: In some countries a 0.17mm cover glass corresponds to a designation of #I%.
A cover glass (0.4mm thick) for blood counting, etc. can be used with Olympus objectives
except D Plan 40X, S Plan Apo 40X and S Plan 100X.

Specimen Slide
(
Specimen slides 0.8 mm to 1.5 mm thick are
recommended for Olympus objectives.
Specimen slides 0.8 mm to 1.2 mm thick are
recommended for the darkfield condenser
and the differential interference contrast con-
denser.
3) Bring the portion of the specimen for obser-
vation into the light path by means of the
low drive control knobs. (Fig.

The specimen holder can accommodate two
standard specimen slides simultaneously.
The specimen holder is removable to obtain
a large unobstructed stage surface to hold
specimens up to
55
mm x 85 rnm.
To rotate the stage loosen the stage clamping
screw
@
and holding this screw, rotate the
stage into the desired direciton. (Fig. 9)
Q Stage clips for use with immersion objectives.
(Fig. 10)
A pair of stage clips are optionally available
to hold the specimen on the stage, eliminat-
ing a specimen drag caused by immersion oil
between slide and stage surface. The clips
can be inserted into the holes
@
provided
on the specimen holder.
