Hi mgnax, welcome aboard!

I have the non BD version and I'm pretty happy with it

Excellent images, even more when knowing how fast are these animals

At the two first ones, are they fighting or trying to mate?

... the results and the infinity possibilities of experimentation of the GNU appeal to me even more than oblique lighting. GNU? Gradient Universal Filter is oblique illumination although done in an imaginative and very useful way. Be aware of the oblique, phase, Rheinberg or DF plates must be place...

I was referring to the dark field condenser, I suspected that it was an oil immersion condenser like Ichty clearly stated. It won't work at all without oil between the top condenser lens and the slide. If it is 1.2 -1.4 model this means that it will work with objectives with NA smaller than 1.2 (alt...

Hi Tonikon, welcome aboard! (Ichty was writing at the same time, but he's faster :D ) This is a very nice old microscope with top optics for its time. But it is about 65-70yrs old and, as you can understand, techniques have evolved quite a lot (just compare a 1955 car with a today one... they do bas...

So, fun fact, this actually doesn't work on the smz-10. The nominal 0.6x reduction in the trinoc port means vignetting occurs with a viewing eyepiece combined with a 40mm lens on aps-c. It actually shrinks towards the middle of the zoom range and then reexpands at the end. In the mean time my optip...

Que voulez-vous dire par attention particuliere ? Ol est delicat a utiliser ? Comme lentilles j'ai des Raynox Dcr 150 et 250. Vous avez une idée du prix moyen pour un LMPlanF N 20x Olympus ? I use the Olympus LMPlanFl 20x 0.40 (not the N UIS-2 version but the older UIS) and it is very good, I don't...

Very nice subject and image.

I wonder if you could be able to show a deeper stack, a stereo pair also would be most enjoyable

Interesting post, this is a somewhat complex world, often unnecessarily arcane. So my question is this: is there in some dark corner of the net a "filter bible" that some tormented soul who has been fighting these same ghosts has compiled? I appreciate the sense of humor. I don't think that anyone h...

Higher resolution (0.65 NA) but much shorter working distance

Any chance of making a stereo pair of the S. spiralis? It seems an excellent candidate!

Hi Mike,
In most cases it can stop at this phase, I hope this will be yours.

Best wishes

Hi, Could this be a good lens for our photography work https://www.ebay.com/itm/163710772822 It needs complementary aberration corrections done at a dedicated compensating eyepiece, so they only would be convenient with the adequate microscope, not for macro style work. More recent Olympus UIS and ...

Thanks, maybe that's the key. Possibly the de-ionised water has a lower surface tension than tap water because of a lack of impurities, it certainly seems to flow more freely on a surface, which would help reduce bubbles. Dave It could be, although I lean to think more about the composition and str...

.. The objective offered here is highly specialized: phase contrast and designed to look through 1.2 mm of cover glass. It is not suitable for use as an "extreme macro" objective with normal un-covered subjects Its typical use is with inverted microscopes to view through the bottom of a Petri dish ...
