Microscopy Procedures

• If the microscope has not been assembled, first refer to Chapter III, "Assembly."

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.

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.)

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.

The arm moves down by turning

the focus knob towards the

observer.
