OPERATION: 

1.

 

Illumination: 

Turn on the power switch; adjust the brightness adjusting knob slowly to the desired level. In 

commonly instance, don’t let it reach the lightest state, otherwise, that shorten the life of the bulb. 

2.

 

Focusing: 

Begin observation of your specimen with the 4× Objective. Turn the coarse focusing knob until a 

clear image is obtained, then use the fine focusing knob to enhance the observation of the 

specimen to its clearest image. When the desired view is obtained under the lowest power (4×), 

rotate the nosepiece to the next higher magnification (10×).  The nosepiece should “click” into 

position. You can obtain clear image with a little fine adjustment.  

It is important to remember when adjusting the focus that the objective should never touch the 

specimen.  When increasing to 100× magnification, the objective will appear to be very close to 

the slide.  Because the 100× is an oil immersion objective, a drop of cedar-wood oil or other 

immersion oil should be applied in the gap between the objective and the specimen.  (Note:  All 

slides should be prepared with cover slips over the specimen for observation under the 100× 

objective.)  The 100 × oil immersion objectives should be wiped off with a piece of soft clean 

cloth or lens tissue to remove the immersion oil immediately after using. 

3.

 

The center of objective superposition with the rotatable mechanical stage: 

When the sample is clear enough, find a clear object and let 

it coincide with the point of cross. Turning mechanical stage, 

if  axes  of  objective  don’t  coincide  with  the  center  of 

mechanical  stage,  the  point  of  object  will  circumrotate 

around “S”. The track is circle, and adjust center of objective 

to let “O1” move to “S” to see if they coincide or not. If not, 

please adjust them. 

4.

 

Adjusting Abbe condenser: 

1)

 

The Abbe condenser can be moved up or down by 

turning condenser focusing knob. When using high power objectives, better to making 

the condenser up and whereas making the condenser down. Iris diaphragm should be 

adjusted according to objective’s numerical aperture, in order to obtain better effect. 

2)

 

Take off the eyepiece to observe the center of aperture diaphragm on the condenser 

overlay with center of objective's aperture. If both is away, may be adjusted the 

condenser center adjusting screw until both is superposition.
