Re: Advice on 20x finite objective

Hey guys, there is a thing I want to mention about the ELWD and SLWD Nikons. The Nikon M Plan 20 0.35 210/0 SLWD can be used at 160mm without any compromises in quality. The Nikon M / BD Plan 20 0.40 210/0 ELWD can not used this way and will give bad results. The only ELWD objective that can be used...

How important is exact compliance of tube length?

Hey guys, I shoot via direct projection on the camera sensors. I therefore use finite 160mm Nikon CF/CFN Planapos. It’s pretty hard to get the accurate to 1mm tube length with extension rings. Are Planapos prone to slight deviations of 1mm to 4mm? Especially if you use different cameras with differi...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

I do not own nor have I tested the Planapo 40 0.95, but a friend once sent me some Diatom comparison photos between the CFN PlanApo 40x 0.95, CF Fluor 40x 0.85 and a CFN Pol 40/0.65 with DIC illumination on an Optiphot 2 set to both maximum exctinction and a mid gray for maximum detail. I would nee...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Hi, I like the Fluor 40/0.85. It's meant for fluorescence applications, but it's very useful for pondlife and vintage slides because of the very long working distance of 0.37 mm. It's got a correction collar that the Plan Apo 20/0.75 doesn't have (WD 0.64 mm) but the working distance is longer than...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

I use the CFN Planapo 4 0.20 for overview as well. I also use it often on larger botanical and histological slides, where it shows his muscles-> very sharp and contrasty. I would rather wait a bit longer and pay more for the CFN versions. If you need high NA I would rather choose the dry CFN Planapo...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Hey guys, I‘ll do a short overview of the CF / CFN objectives I own (or owned): Nikon M 5 0.1: -> this is not the M Plan and is for a tube length of 160mm. Oldie but goldie! Zero CA. Probably a predecessor of the Nikon M Plan 5 0.1 210/0 -> it can be used with or without coverglass and is especially...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Ah, ok. That’s really thick. In ~1945 the standard coverglass thickness was changed from 0.18mm to 0.17mm. In the 1800s there was no standard thickness, so 0.20mm is not a surprise. The problem may not only be the thickness of the coverglass. It’s the glass quality and the quality of the mounting me...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

The 60 0.95 is definetely really impressing, but sadly hard to handle. Despite most coverglasses seem to be 0,15mm, the 60 0.95 works best at 0.175mm on most of my slides. Nonetheless the image is good at 0.17mm or even 0.165mm, too. But if you look very closely with camera zoom or high magn. eypiec...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Hey, that’s funny:) You’ve really nice images in your Feed! Is there really such a huge difference in contrast? The specimen in the picture taken with the 40x almost looks translucent compared to the image with the 20x. Most antique slides have coverglasses of about 0,18mm, which is not that cool fo...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Hi Pau, I edited my post and named the objectives. I tried to get the same focus point, but that’s very very hard, small differences are mostly present in such comparisons, but were not made on purpose by me. I made another comparison on a coscinodiscus sp. The images are only adjusted in brightness...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

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 DI...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Oddly enough, I am moving to the Olympus short-barrel PlanApos. I lucked upon a Vanox AH with DIC for a great price, and started to collect short-barrel PlanApos mostly because I was interested to see if the DIC would work better with objectives from the same era than with my Nikon CFs. Plus they p...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Hey guys, thanks a lot for your help! I‘ve a Nikon CF Planapo 40 1.0 and a CFN Planapo 60 0.95. Both are absolutely amazing in brightfield and PZO Pluta DIC. That’s why I thought the 100x Planapo may be worth it for me, but I will get a Planapo 60 1.4 or a Neofluar 40 1.3. I have a Zeiss Planapo 100...

Nikon CFN Fluor / Planapo 100 160/0.17

Hey guys, you guys helped me a lot so I hope someone can answer my question. I have a Nikon CFN Fluor 100 1.3-0.8 160/0.17 and I like it. Because of the Iris I will definitely keep the Fluor either way. The CA correction is very good for a Fluor objective. Is it worth to upgrade to a Nikon CFN Plana...
