Hi guys,
Who has experience with this objective, is able to compare it to the equivalent planapos in brightfield?
I'm lucky to have Olympus splanapo optics (including 60x/1.4) at work, but am trying to get my personal Leitz Diavert up to the same standard. I'm afraid the leitz planapo 63 oil is out of my league, but I am open to offers.
Thanks, best wishes,
René
Hi René,
Do you mean the
Leitz 63/1.3 OEL Fluoreszenz
or the
Leica 63x/1.30 Oil ? ;)
I have tested the 25/0.75 Oel Fluoreszenz and the 50/1.00 W Fluoreszenz. They had excellent resolution and very low spherical aberration, as expected. But they are achromats and have strong colour fringing. Nothing like the PL APO.
I think the (N)PL Fluotar 50/1.00 Oel or the (N)PL Fluotar 100/1.32 Oel would be better choices.
Kind regards,
Jon
Hi Jon,
No, a 100x will not do on an inverted microscope with lowish condenser aperture. I do have a Leitz 40x oil, so I'm sorted for the 40-50x range. I know there is a 25x/0.75 oil NPL fluotar, I thought (hoped) it would be more or less similar to the Fluoreszenz types. But apparently it is not in the same leaque.
Thanks for the info,
René
Hi Jon,

I have the 50 WI as well and I find it an exellent objective with very little colour fringing. The image of the 50 WI I found nearly as good as that from the NPL Fluotar 50 oil I once had. Best regards,
Rolf
