B.  Interpupillary adjustment. 

 

1.  Looking through the eyepiece (1), move the eyepiece tubes (3) by taking hold of the prism 

housing (4) and moving out, or inwards. 

 

2.  Interpupillary distance is correct when the two fields of view viewed through both eyepieces 

appear complete and are unified into one.  

 

3.  Interpupillary distance should be adjusted for each new user.  

 

C.  Focussing 

 

1.  Turn the zoom knob (16) to the lowest magnification 1X. 

 

2.  Place a flat object or a microscope slide on the centre of the stage (11). 

 

3.  Turn focussing knobs (18) to mid-focus range.  

 

4.  The head holder (17) is mounted on a column (21), on which it can be moved up or down, 

depending on the size of the object to be focussed on. 

 

a.  Support head holder (17) with one hand without touching any lens, and with the 

other, loosen the screw (20) on the support collar (19). The head holder can then 

be slid to the base (13). 

 

b.  Without letting go of the head, loosen the head holder locking screw. (Fig. 1). 

 

c.  While looking through the eyepiece, move the head holder up or down until the 

object appears in focus.  

 

d.  Tighten the head holder locking screw. Do not let go of the head yet.  

 

e.  Slide the security collar up to the head holder, and tighten the support collar 

screw. The head can then be released.  

 

f.  It is not necessary to adjust the head every time the sample is changed, only 

when it appears out of focus.  

 

5.  Adjust the focus knobs, (18) until the image appears sharp.  

 

D.  Diopter adjustment. 

 

Diopter adjustment collars are located on the eyepiece tubes. Their normal position is when the 

lower part of the collar is aligned with the sign marked on the eyepiece tube. 

 

For differences in eyesight: 

 

1.  Using only the right eye, look through the right eyepiece (1) and adjust focus. 

 

2.  Next, using the left eye, look through the eyepiece and adjust the focus by turning the diopter 

adjuster (2) located on the left-hand tube (3) until the image appears sharp. Do not use the focus 

knobs to adjust focus (18).
