Alexander you said: "I am not perfectly sure and did just a guess." Well, you're right, it's a Nomarski prism. I put a polarizer on top and this is the result.
Thank you
Steve

Maybe this new pictures will help. As far as I know is related to the CARL ZEISS NEOPHOT 21 but I am not shure.

INKO EPI CARL ZEISS FILTER
Need help figuring out which Zeiss microscope model this filter INKO EPI was used on. The glass of the second circle (close to the screw) slides if the screw at the top is guided. At the top the one I found in internet, is smaller (body 4.5cm the INKO EPI 7.5 cm)

Re: Brand of this old condenser?
Leica was not a microscope company until the 1991 merger. This condenser easily could be Leitz but not Leica. It is not a DF condenser.. It is a stacked BF condenser with sectional N.A. increases matching that required by the grouped objectives coupled to it's matched system. A DF condenser has to ...

Re: Brand of this old condenser?
Apochronaut, look what I found. Looks very similar, maybe the brand is Leitz. (I made similar pictures for you but the piece at the back is not a Leitz)

Re: When these lenses were manufactured by E.Leitz?
Is the 6 not just a partial? Yes, it is empty. Again thank you apochronaut for your precious help. Thanks to the clues you have given me, I believe that the lens was possibly sold from the year 1914 onwards. On eBay there is one with the serial number 169234 from the year 1916 with the lens No. 3 v...

Re: RARE ADJUSTABLE ATTACHMENT FOR MICROSCOPE OBJECTIVES BASE
Sometimes the objectives are very short, only about 1 cm. long. These were usually used when a vertical illuminator was placed between the objective and microscope body tube. Since the vertical illuminator increased the tube length, the upper part of the objective barrel which in the pre-plan era w...

I have found very little information about these filters that has reached me. Any information would help me.
So far I know that it is from the Lomo brand and from the little that is found on the internet it must be very old.
Thank you
