5.5  Adjusting the stand 

Torque of the focus wheels 

You adjust the torque of the focus wheels by holding one of the two wheels in place 
and using the other hand to turn the other wheel.  
Depending on the direction of the turn, the torque will be increased or decreased. 
On one hand, this function can help to make it easier to adjust the focus and on the 
other hand it can prevent the microscope head from slipping down unintentionally. In 
this way you can avoid possible damage which could occur if the objective lens and 
the object being observed should collide. 

Height adjustment 

Fixing the microscope holder 

With  a  stereo  microscope  on  a  pillar  stand,  the  microscope  head  can  be  height 
adjusted using the focus wheels and in addition, the microscope holder can be fixed 
at any point on the pillar, depending on the application requirements. 

To primary way to fix the position is to use an adjusting screw (1) on the holder. 

There  is  a  metal  ring  which  also  ensures  sufficient  grip  and  which  is  fixed  with  a 
second  screw  (2)  under  the  holder  on  the  pillar.  This  metal  ring  proves  to  be 
particularly  useful  when  the  screw  (1)  on  the  holder  is  loosened,  to  swing  the 
microscope head to the side.
