Microscopy Procedures
1
Place the sample.
Place the sample in the optical path on the stage plate of the stand.
The black or white side can be chosen depending on the sample.
Use the stage clips to hold the sample, if necessary.
2
Focus on the sample.
Turning the left and right focus knobs to the same direction will raise or
lower the arm (on which the zooming body is mounted) and focus on the
sample.
■ Working distance
The distance between the focus plane and the bottom surface of the
zooming body is called “the working distance”. Since the working
distance of the SMZ745T is 115 mm, the focusing will become easier if
you set the zooming body at the position where its bottom surface is 115
mm apart from the sample surface. Refer to Table 1 (p.23) for changing
the working distance when the auxiliary objectives are attached.
■ The torque of the focus knob
If the torque of the focus knob is too light, the
zooming body falls down by its own weight.
Adjust the torque to an appropriate weight.
(Refer to “7. Adjust the torque of the focus
knob.” on p.14.)
3
Adjust the interpupillary distance.
This adjustment is for adjusting the distance
between both eyes of the observer.
Adjust the interpupillary distance so that the
fields of view for each eye are merged into
one. Move while holding each sleeve with
both hands.
This adjustment is required for each observer
since individual interpupillary distance vary.
• If the microscope has not been assembled, first refer to Chapter III, “Assembly.”
The arm moves down by turning
the focus knob towards the
observer.
