Troubleshooting

Depending on how you use, the performance of this microscope may not be exhibited, though they are not failure. If

problems occur, please review the following list and take remedial action as needed.

If you cannot improve the phenomena after checking the entire list, please contact us for assistance.

6.1 Optical systems

Phenomena

Even though the lamp lights, the

field of view is dark.

Though the brightness control

knob or the light volume

adjustment dial is rotated, the

illumination does not become

brighter.

The peripheral area of the field of

view becomes dark. Or, the

brightness of the field of view is

not even.

Dust or dirt is visible in the field of

view.

The observation image glares.

The observation image is viewed in

white haziness or not visible

clearly.

6. Troubleshooting

Cause

The aperture diaphragm and the

field diaphragm are not opened

sufficiently.

The analyzer or the polarizer is in

the light path.

Light path selection lever of the

trinocular tube is at the

position.

The observation method selector

knob or lever or the turret is at the

halfway position.

The shutter is engaged in the light

path.

The halogen bulb or the mercury

burner is burned out.

The light path selection lever of the

trinocular tube is not stopped at

the correct position.

The observation method selector

knob or lever or the turret is at the

halfway position.

The objective is not correctly

engaged in the light path.

The nosepiece is not attached

correctly.

The filter is not engaged in the

light path correctly.

The analyzer and the polarizer are

not inserted correctly.

The eyepiece, the tip of the

objective or the sample is dirty.

The aperture diaphragm is

narrowed down too much.

The objective for UIS2(UIS) series is

not used.

The dummy slider is not inserted in

the nosepiece.

Remedy

Open the aperture diaphragm

sufficiently, and open the field

diaphragm until the field

diaphragm circumscribes the field

of view.

Remove the analyzer or the

polarizer from the light path.

Set the light path selection lever of

the trinocular tube to the

or the

position.

Select the observation method

selector knob or lever or the turret

surely.

Remove the shutter from the light

path.

Replace the halogen bulb or the

mercury burner.

Stop the light path selection lever

of the trinocular tube at the

position where the clicking sound

is heard.

Select the observation method

selector knob or lever or the turret

surely.

Turn the nosepiece until the

clicking sound is heard and engage

the objective in the light path.

Push in the nosepiece along the

mounting dovetail until it touches

the end, and secure it.

Stop the filter at the position

where the clicking sound is heard.

Engage the analyzer and the

polarizer in the light path correctly.

Clean them sufficiently.

Adjust the aperture diaphragm

according to the numerical

aperture of the objective to use.

Replace with the objective for UIS2

(UIS) series.

Insert the dummy slider in the

nosepiece.
