5.6  Using eye cups 

 
The  eye  cups  supplied  with  the  microscope  can  basically  be  used  at  all  times,  as 
they  screen  out  intrusive  light,  which  is  reflected  from  light  sources  from  the 
environment onto the eyepiece, and the result is better image quality. 
 
But  primarily,  if  eyepieces  with  a  high  eye  point  (particularly  suitable  for  those  who 
wear glasses) are used, then it may also be useful for users who don’t wear glasses, 
to fit the eye cups to the eyepieces. 
 
These  special  eyepieces  are  also  called  High  Eye  Point  eyepieces.  They  can  be 
identified  by  the  glasses  symbol  on  the  side.  They  are  also  marked  in  the  item 
description by an additional “H” (example: HSWF 10x Ø 23 mm). 
 
When fitting the eye cups, make sure that the dioptre setting is not moved. We would 
therefore advise that you hold the dioptre compensation ring on an eyepiece with one 
hand while you fit the eye cup with the other. 
 
Before  using  the  microscope,  users  who  wear  glasses  must  remove  the  eye  cups, 
which you may find on High Eye Point eyepieces.  
 
As  the  eye  cups  are  made  of  rubber,  you  must  be  aware  that  when  you  are  using 
them,  they  can  become  slightly  dirty  through  grease  residues.  In  order  to  maintain 
hygiene, we would therefore recommend that you clean the eye cups regularly (e.g. 
with a damp cloth).
