You mean the Vanox AH-2, right? That huge, electronic monster of a scope from the 1980's? Yes, they do seem to come with DIC quite often. And the DIC with SplanApos looks incredible, especially in the hands of people such as Anne Gleich. Since they were so expensive, I guess the added expense of DIC was seen as marginal.Soki wrote:
Now thats comprehensible. There seem to be some Olympus Vanox with DIC for sale out there, because they were probably used often with DIC. This DIC looks really awesome, especially in combination with SPlanapos.
Congrats for the great deals! The prices for these lenses are really low. The standard Splanapos are much more expensive.
I choose the PZO Pluta DIC manly because of the comparable low price and it’s flexibility. The results with the Nikon CFN objectives are pretty good:

but the popular Systems (Zeiss, Nikon, Olympus, Leitz/Leica,..) outperform the Pluta. The possibility to use nearly every finite (maybe infinite as well?) objective out there is pretty unique, but of course will not deliver the same results as perfect matched prism designed for a specific objective.
I have the Nikon CF M Plan 20 SLWD and the 40 ELWD and they are great objectives, but they are far from being CA-free. I had the Nikon CF Plan 40 0,70 and was pretty disappointed. The image wasn’t satisfying. A very old (but really good and nearly CA-free) CZJ achromat (40 0.65) performed equally, even with direct projection. That’s the reason why I sold it.
My Nikon CF/CFN Planapos however are absolutely mindblowing. I didn’t think a high NA dry objective (60 0.95) can perform so well. I immediately sold my Zeiss Neofluar 60 0.90.
Learned quite a lot through this discussion here, glad this thread evolved this way:)

My scope, however, is the earlier, 1970's Vanox AH, from the BH era. It's shown here:

I plan to provide an update on it soon, it has evolved quite a bit.
The DIC is very good at 40x and 100x, but less good at 10x in my experience. I could probably learn to dial it in slightly better - I regret to say that I've spent much more time buying and building things for it than actually using it. But I do think that the systems with a single objective prism makes it hard to get perfect DIC at all magnifications, as the interference fringe can't match the BFP of both high and low magnification objectives equally well. I kind of wish it was possible to shift the objective prism vertically, as in the PZO system. Your results with this system looks really good to me.
I'm curious to hear you like your CFN PlanApo 60x 0.95 so much. I have the earlier CF PlanApo 60x 0.90 and find it a little underwhelming. Resolution and sharpness is good, but the contrast is pretty low. Do you find the 60x 0.95 contrasty? Or do you just increase contrast in post?
I too like how this thread evolved, and learned a lot!
