OZL-45-BA-e-1510

Assembly 

The first step is to position the 

microscope stand on a firm, level surface

The holder

 is already on pillar of the stand, but you must always check whether it is 

fixed

 securely and that it is in the 

correct position

 (preferably centrally and facing to 

the front). 

Please see section 5.5 for more details on adjusting the stand. 

The  next  step  is  to  place  the 

microscope  head  on  the  holder

,  by  passing  the 

objective through the holder ring until the rest of the head is above the ring.  

You must use the small silver adjusting screw on the front of the holder ring to 

fix the 

head

 in place.  

The alignment of the microscope head is left to the user to do and can be adjusted to 
suit the individual application situations.  
To  make  it  easier  to  operate  the  focus  wheels  or  lighting  control  for  example,  we 
recommend that you position the head with the tube connectors centrally to the front.  
Ideally,  the  holder  and  head  are  then  parallel  on  the  central  axis  of  the  stand  base 

(see figure on page 9).

 

Now  you  can 

remove  the  protective  caps from  the  tube  connectors

  so  that  you 

can then 

fit the eyepieces

. When doing this, please be particularly careful that you 

do 

not  touch  the  optical  lenses  with  your  fingers

  and  that  no  dust  enters  the 

apertures. 
You should also 

never fit two eyepieces with different magnifications

With regard to the use of 

transmitted light illumination (OZL 451)

 you must make 

sure that the 

frosted glass stand 

inlay

 is fitted in the centre of the stand base

so that the transmitted light can be used correctly. 
It is always best to 

fix

 the different 

stand inserts

 using the 

adjusting screw

 on the 

front side of the stand base. 

Additional optional attachments: 

The  eye  cups  supplied  with  the  microscopes  can  be  fitted  to  the  eyepieces.

(see section 5.6)
