Interference contrast? Interphako or Jamin-Lebedeff or Mach-Zehnder

#1 Post by tardigrade37 » Thu Jan 16, 2020 7:07 pm

Hi all,

Does anyone here use these methods? I have a ZEISS Jena Perval with Interphako that has some misalignment issues that have prevented me from extensive use. I also have a full Jamin-Lebedeff setup, but it is finicky. I would love to add a Leitz Mach-Zehnder to my collection, but those are hen's teeth!

I would love to find others using these unique techniques.

I have a Jamin-Lebedeff condenser but no matched objectives and beam recombiners. Its a set of techniques I'm quite interested in learning more about and trying for myself but as you said these are extremely difficult to find. If its not too much I'd love to see your Jamin-Lebedeff set and some microscopic images taken with it along with your personal impressions.

Hi Wes,

Yes, I would be happy to share my experiences and some photos. It will take a bit for me to get everything set up again..

Coincidentally, a complete JL set just showed up on Ebay, the first I have seen in years. The price tag is quite steep, but I suspect most of these are now in the hands of their permanent owners.

Nice, I'm looking forward to seeing your work.

I saw the JL set, looks really cool but $5000 would leave a hole too large for my hobby budget.
