Hello PeteM,

I'm new to the forum and I don't think I can send you a personal message.

I'm interested in the "Set of GF Zeiss Jena PhV objectives" that you mention. You have only the objectives, right? What are the objectives?

Thanks,
Andrey

Andrey,

The set of four Zeiss Jena PhV objectives I have are all Planachromat GF (wide field) infinity. There's a 12.5x, 25x, 40x, and 100x. These have a 25mm mount and the 100x is longer than DIN. By design, the 100x is apparently longer either to incorporate all the extra glass in a wide field plan phase objective or to minimize oil contamination.

I've tried these on both a Leica DMLS and a Nikon E600, which use the same 25mm thread and are infinity. It's likely they would work on M25 to RMS adapters, being infinity and happy to accommodate a longer tube length, but I haven't tried that.

As you probably know, the Zeiss Phv type of phase contrast is somewhat unique in having two phase rings. One can use just the inner one and use the condenser aperture to block off the outer one for some specimens. Or use both annuli and the Phv condenser for maximum contrast. I don't have the matching Zeiss PhV condenser, but have achieved decent phase contrast by matching up a single inner phase ring with various annuli I have on hand.

This is what they look like: https://www.ebay.com/sch/i.html?_from=R ... n+kliton77

If this is what you are looking for and have something to trade, great. If not a trade, I'd sell them for a fraction of those Ebay prices.

Thanks for the details and your experience with the objectives. I'm aware of the Jena GF infinity system but have no experience with the PHV. Recently I acquired a Jenaval microscope in good condition but only with bright field objectives. I'm interested in the lower magnifications 12.5x and 25x. For trade I can offer from the same CF250 line the Planachromat 20x 0.40 oo/0.17-A and Planachromat HI 100x 1.30 oo/0-A. I don't need the 20x because I also have the POL version. And 100x is out of my magnification preferences. Even 40x is too much for me :)
Let me know if you need those or if you're willing to sell only the 12.5x and 25x objectives. Have a nice day!

Hi a.kat -- It probably only makes sense to trade or sell the four Zeiss Phv phase objectives together. Wouldn't need more in trade. Would sell the lot of four Zeiss GF plan infinity phase objectives for less than current Ebay listings for a single one of that type of objective. Once you post a bit more I believe we can send messages.

Hi PeteM,

I agree and I would have done the same I guess! Hopefully I will be able to contact you soon via PM.

Several changes to the above list.

Still hoping to find some Nikon Eclipse DIC stuff and a couple Leica prisms.

Several items previously listed are gone.

Updated. A Leica "K2" condenser prism for the DM series scopes is now top of the want list. Several items for trade no longer available, a Leica DIC (ICT) scope added.

Hi Karol,

I suspect that safe shipping to Poland would make it uneconomical for both of us. Especially now. I know, for example, that I can't even get parts sent from Germany to the US unless it's a very pricey shipment method. What I have is a complete stand, with all sorts of options for binocular or trinocular heads, teaching heads, plus sets of Achro, DPlan, SPlan objectives, phase contrast, etc.

I'd urge you to try to find something nearer, maybe German Ebay? If that fails after a while, feel free to message me.

You might also consider an Olympus BHT (same removable nosepieces as the BHS) and a LED upgrade to get the lamp closer to the brightness of a BHS.

Just updated the want list - now down to mainly wanting an "L" prism for Nikon Eclipse C-CU condenser and a "K2" prism for Leica DM DIC.

If there's interest, I've been trying to assemble a range of DIC scopes and will soon be able to offer at least comparative impressions between Nikon and Olympus finite DIC, and AO, Leica, Nikon, and Olympus infinite DIC. Don't have any Zeiss experience and if there is ever a thread comparing systems, hope someone else could contribute there.

Hello PeteM,
Brand new member, so I can't PM you. Would you be willing to share pics, descriptions, etc., for the Biostar gear you have available? Trying to refurb mine, and looking for as much bling as I can find :)

PM sent. The extra stuff is mostly A.O. for scopes other than the (complete) Biostar.

Bump - still looking for a Leica K2 prism and a Nikon L prism - as noted above. Lots of stuff as possible swaps (objectives not listed above, heads, etc.). A couple scopes gone, couple added to the list above.
