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...

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...

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...

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...

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...

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...

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...

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...

Hey John, here’s the QuickStart guide: 1. put the handle of the prism ton on „0“ 2. rotate the Pol analyzer of the prism ton to the red marked „45“ 3. set the prism condenser to „0“ 4. „köhler“ the illumination 5. cross the original polarizer or another high quality polarizer to highest possible ext...

You’re welcome:) there are so less output pictures around. I used a Nikon CFN Planapo 60 0.95 160/0.11-0.23 without an eyepiece. I used it with the „40“ condenser prism. Minutes ago I used it a Zeiss Planapo 25 0.65 169/0.17 and a KPL8 with condenser prism „20“ with very good result. Thiamin the mos...

Hi guys,

I got my new pluta system and I'm super happy with it. If you have any questions about it, please let me know. The pictures are only cropped and sharpened after the strong compressing. No other post processing to show the unadulterated possibilities of this system.

best,
Simon

Hi, i can only recommend petroleum ether of highest purity, called Benzinum medicinale. I get mine from the drug store for a few bucks (Germany). They fill me up a bottle of 100ml. The surgical spirit from boots contains oil besides other ingredients and therefore isn’t suited for this purpose. The ...

Hi, i always use surgical spirit for cleaning in combination with soft toilet paper or a soft cloth. After that I use an air blower bellows (normally used for sensor cleaning) to remove any particles left. Surgical spirit is very good for removing immersion oil, too. Even the lacquer ring of very ol...

Thanks a lot for the link, I bought a pair WF 10/22 from another chinese seller. They’re probably produced in the same factory and hopefully differ only slightly. https://www.ebay.com/itm/WF10X-22-Eyepiece-for-Biological-Microscope-High-Eye-point-Diopter-Adjustable/184362673645?pageci=8e0ace51-15bd-...

Hey guys,

thanks a lot for your help! I managed to get it out. This was definitely not made to remove.

best regards,
Simon
