This is description of this part:
The PZU UFC is a universal set that allows for simple polarization, dry darkfield, and phase contrast at 20x and 40x magnification. Phase contrast is achieved by placing a disc with the appropriate aperture on the condenser - and this is just such a disc.
What is this part needed for?
- if this is the item you're missing from your PZO UFC kit
- if you have a PZO A, Ph, Pha, or Phs phase contrast lens with 40x magnification, you can use this insert to achieve phase contrast without installing the entire phase condenser
