Wanted aplanatic-achromatic 1.4na Condensor top for Leitz universal condenser

[einman]

I have a separate turret for my Leitz Diaplan that I have been filling with strictly oil immersion objectives. My most recent acquisition being the 25X/0.75 na fluor immersion objective. With the addition of this objective the turret now has a 25X/0.75 fluor; 40X/1.4 na Fluor; 63x/1.4 na Fluor and a 100X/1.32 na Plan Apo. It has taken me 2 years to slowly purchase these objectives. The only dry objective on the turret is a 10x/0.30 Fluor. I wanted a turret with only oil objectives to eliminate the possibility of ruining my 40X dry planapo objectives etc. The Leitz Diaplan has quick change turrets. I have three turrets one with dry objectives, one with phase-contrast and the oil immersion.

While these objectives offer superb images the fact I only have a 0.90 achromatic condenser means I could potentially squeeze more resolution out of them. I need the aplanatic-achromatic top na 1.4 for my universal condenser.

With that said if anyone has one or happens to come across one for sale please let me know.

Only Aplanatic, and NA 1.25 but is this the sort of thing you mean?
