More about part: Carl Zeiss Jena Phv Apl 0,9 variable phase contrast condenser - phase ring (diaphragm) for 16x microscope objective (ID: 99195)

Why do you need this?

• if you have a condenser without this ring
• if in the condenser you own this phase contrast ring has been damaged (for example the glass has cracked or the rings glued onto the glass have worn out)
• if you are configuring an unusual combination of rings in the condenser yourself
• if you want to use this ring outside the condenser - for example as a slide insert, in a filter holder or by placing it on the illuminator
• if you want to print such rings yourself on a 3D printer and need a reference sample
