 Focusing on the specimen 

 

10.1

 

Focus on the specimen 

Focus  on  the  specimen  using  the  10x  objective.  To  avoid 

touching the specimen during focusing, you should raise the 

stage  to  its  maximum  height  adjustment  and  observe 

whether  it  is  close  to  the  objective  at  first,  then  using  the 

fine  focus  slowly  lower  the  stage  while  observing  through 

the eyepieces until a clear crisp image is seen. 

 

10.2

 

Condenser adjustment 

 

Turn the condenser focusing knob to move the condenser up or 

down.  Raise  the  condenser  when  using  the  high  magnification 

objectives,  and  conversely  lower  it  when  using  a  lower 

magnification objective. 

 

The  condenser  and  objective  are  coaxial.  The 

condenser  has  been  adjusted  and  pre-set    before  leaving  the 

factory, and the maximum height has been pre-set, so the end-

user has no need to adjust it oneself. 

 

 

10.3

 

Aperture Iris Diaphragm Adjustment 

Turn the aperture iris diaphragm lever to adjust the aperture iris 

diaphragm. 

 

The aperture iris diaphragm is designed for the 

adjustment of the numerical aperture, not for 

brightness. 

 

Generally, setting the aperture iris diaphragm to 70 % – 

80 % of the numerical aperture (N.A.) of the objective 

in use will provide an image with good contrast. If one 

chooses to observe the image of the aperture iris 

      diaphragm, one can remove one eyepiece and look 

      down  the  eyepiece  tube.  One  will  observe  a  dark  ring               

encroaching  from  the  sides  of  the  tube  at  the  end  of  the 

viewable range.
