I've had this condenser for a long time, but never took a good look at it until recently. My guess is a nicol prism polarizer due to the squarish prism inside and the fact that it modulates my computer screen. It has an oil cap. Is this an old Leitz condenser? Both irises work fine.
Thanks for any info.

It seems an old Leitz condenser later adapted for more recent microscopes like the Orthoplan, note the brass sliding dovetail looking very different of the other parts.
You can test if it's a polarizing prism crossing it against another polarizer (or looking through it to a phone or computer screen if you don't have a polarizer)

Thanks guys. Still a question about who made the thing. Being familiar with Leitz, it seems odd they would have made something without putting their name on it.
Yes, it is a Leitz dovetail and fits on my Diavert condenser fork.
I guess the next step is to give it try. I'm thinking paramecia between crossed polarizers
Not sure why this would be better than simply sticking a polarizer over my Heine--which is what I normally do.

If one has access to a lathe and some standard cutting tools, this kind of adapter is not hard to make. I had one made. I made a drawing and a more experienced friend made the bulk body with a standard lathe. Some additional work with a tiny saw and it was done. I did not do the dovetail but an adapter to use Leitz sleeve type condensers on another brand. Mine is aluminum but brass is also soft and easy to work on.nanometer wrote:Thanks guys.
