f ) One side of image is blurred. The revolving nosepiece is not correctly
engaged.
Make sure that the revolving nosepiece
clicks properly into place.
The specimen is not correctly mounted
on the stage.
Place it correctly on the stage.
The optical performances (profile irregu-
larity, etc.) of the culture vessel bottom
plate are poor.
Use a vessel with a good profile irregu-
larity characteristic.
2. Electrical System
a) The bulb flickers and the brightness
is unstable.
The line voltage fluctuates. Use a voltage stabilizer.
The bulb is nearly burned out. Replace the bulb.
The power cord is not corrected securely.
Correct it securely.
3. Focusing
a) The coarse adjustment knob is too
difficult to rotate.
The tension adjustment ring is tightened
too much.
Loosen it appropriately.
b) The image goes out of focus dur-
ing observation.
The tension adjustment ring is loosened
too much.
Tighten it appropriately.
4. Observation Tube
a) The field of view of one eye does
not match that of the other.
Incorrect interpupillary distance adjustment.
Adjust the interpupillary distance.
Incorrect diopter adjustment. Adjust the diopter.
Your view is not accustomed to micro-
scope observation.
Upon looking into eyepieces, try looking
at the overall field before concentrating
on the specimen range. You may also
find it helpful to look up and into distance
for a moment before looking into the
microscope again.
5. Photomicrography
a) The image is out of focus. Poor focusing.
Adjust focusing so that the double
crosslines and specimen look clearly
defined.
b) The image periphery is blurred uni-
formly.
If you are using an achromatic objective,
this type of objective cannot bring edges
into sharp focus.
Blurriness is unavoidable.
c) Image cannot be focused sharply. The correction collar is not adjusted.
Adjust the correction collar according
to the bottom thickness and material
of the vessel.
d) The window or fluorescent lamp in
the room is photographed.
The stray light entered through the eye-
pieces or viewfinder is reflected.
Cap both the eyepieces and the pho-
tomicrographic system’s viewfinder.
