PROBLEM REASON 

SOLUTION

 

PAGE 

I、Optical Part:

 

The plug of the lamp holder is 
not connected into the 
illumination set 

Connect them well   

The bulb burnt out 

Change a new lamp 

The brightness is too low   

Adjust to a proper position 

The color filter is piled too 
much 

Minimize the number of the 
filters 

11 

1. The illumination 
is opening, but the 
field of view is dark. 

No use the appointed lamp 
bulb

 

use the specified halogen Lamp 
6V30W 

The nosepiece is not in the 
located position

 

Turn the nosepiece into the 
position where you can hear 
“clicked” 

the color filter is stopped 
midway 

Insert deeply 

2. The edge of the 
field of view has 
shadow or the 
brightness is 
asymmetry 

The phase contrast slider is not 
located in the proper position 

Turn the slider into the 
“clicked” position   

13 

There are stains on the 

specimen 

Change a clean specimen 

 

3.

  Find  dust  and 

stain in the field 
of view

 

There are stains and dust 

on the eyepiece 

Clean the eyepiece 

 

4.  appear double 
image 

the size of the aperture 
diaphragm is too small 

Open up the aperture 
diaphragm 

11 

The nosepiece is not in the 
center of the light path 

  ensure the nosepiece is turned 
into the “clicked” position 

the aperture diaphragm in the 
view of field is opened  too 
large or too small   

adjust the aperture diaphragm 
correctly 

11 

The lens (condenser, objective, 
ocular or  culture dish) 
become dirty   

Clean all 

 

In the phase contrast 
observation, the bottom 
thickness of the culture dish is 
more than 1.2mm. 

 Use a the culture dish whose 
bottom thickness is less than 
1.2mm 

5. Resolution 
problems

 

z

 

Image is not 
sharp

 

z

 

The contrast is 
not high

 

z

 

The detail is 
not clear

 

z

 

 Don’t  obtain 
the phase 
contrast effect 

Use a bright field objective   

Change  to  the  phase  contrast 
objective
