Re: Wanted - Zeiss intermediate rings - and/or dic sliders for standard

I have used the 0,63nA condensor with the 63/1.4 Objective, so it would well for the DIC. But as 75RR explained you waste a lot of the possible resulution of the objective. So for such high numeric objectives better to use the condensor with 1.4NA Frontlense, like this one: https://www.ebay.de/itm/Z...

Hello Viktor, indead - Anne Gleich really makes phantastic photos! I press my thumbs that you will find the S. pluvialis. Another alternate would be that I sent you some resting aplanospores, so you can grow them on your side. But at the moment I am not convident that the cultures will develop well,...

Sperm explosion - Stephanosphaera pluvialis, sexual reproduction

For me observing the algae Stephanosphaera pluvialis has always been a very special, magic or majestetic moment...you understand what I mean if you ever had the change to observe them.

Re: Zeiss 465285 Inko Condenser

A bit of warming up should not be an issue. And as stated, good "grip" with some tools as described is essential, without applying too much mechanical tension. Maybe one more hint: Also you can apply a small dop of WD40 on top of the 0.32NA lens. Right there where you can see the red 0.32 printing. ...

Re: Zeiss transmited DIC nosepiece

1.) Many Zeiss owners (quite rightly) disapprove of this as they are factory aligned and it is a real shame to mess that up. I have retro-fitted and installed several Zeiss nosepieces with DIC stools. Allignment of the slot direction itself is not really the problem. But the retrofitted DIC stools ...

The UV portion of the Halogen Lamp is quite small (see hyperlink below), also there are many glas lenses between light source and human eye. More important is the IR Filter - and this is fitted by Olympus in the lamp housing. https://www.mikroskopie-forum.de/index.php?topic=32598.msg240689#msg240689...

For me I instantly enjoyed working with the KPL 12,5x Objektives (that have a FOV of 18) together with the wide field nose piece. This makes a FOV of 22.5, what I still can observe without moving the eyes. So its relaxing and I like this - it is really big cinerma. I switched to KPL 12,5x Objektives...

No there is no stray light issue. The only thing is that eventually dust may pass into the optics. So it probabely a good idea to close the opening slit, as Microbob has mentioned, tape should be fine if there is no slider available.

They have a lens, not sure what it is/does. Do not remove the lens.
The DIC stools add some additinal "tube length" to the system, so the telan lense is compensating this.

Re: Leukocyte crawling in blood

Wes, how did you actually prepare the slide? Wonder if you added other ingredience, for example an isotonic saline solution? Maybe this was contaminated over the time? the little particles in other videos of fresh blood... so a blood specific thing, suggestions are welcome. This is really interesting!
