1. A condenser wouldn't come with an analyser, that has to be above the objective. Yours does seem to have polarising material in the lower holder.
2. A 'Pol' condenser designation, for the whole thing, and/or the top lens, just relates to the thing being strain-free really. This is the case with the 'P' on that top lens. It is more important if you are taking measurements.
3. In terms of the marking on yours, the polarising material is usually sandwiched between two clear layers of very thin glass. As polar work often requires a high bulb setting, as much light is 'lost' this inevitably can lead to some heat damage. It is not unusual for the material to be 'shot' completely, sometimes being bleached in the inner section. Can't see this in yours, but it may be some delamination.
Hope this helps.

Re: New bought a leitz POL condenser
Not sure what that's showing.. Have you joined a pol and a phase condenser?
You could use a loose sheet of pol matrial and just put it over the light, then use a DF/phase condendser?

Thanks for advise ,It can 旋转 the pol material easily.i can change it back anytime
I did this Just for fun
Re: New bought a leitz POL condenser
旋转 = rotate!
