3.9 Operation the Phase Contrast Microscope 

Phase  contrast  microscopy  requires  phase  contrast  (PH)  objectives  and  PH 
sliders

 

 

 

 

 

 

 

 

If PH Slider is used, it is possible to center the annular diaphragm. Turn the 
centering screw of the PH slider to merge the annular diaphragm image with 
the phase ring image in the objective. 

 
 
 

 

 
 

 

 

 

 
 

 

 

 

Decentering the phase ring and the PH annular diaphragm

 

Basically, the phase ring and the PH annular diaphragm should be adjusted so 

that 

they are concentric

However, slightly decentering them will produce a shadowing 

effect, resulting in a three-dimensional image.
