Re: Finally Acquired a Nikon SMZ-U

Thanks for the detailed reply, einman. I can relate to pretty much everything you said. I have a fairly ridiculous collection of microscopes myself, some of which are VERY nice (got incredibly lucky), but I'm always drooling over something even nicer. :roll:

Re: Finally Acquired a Nikon SMZ-U

I am excited. I have wanted one for several years. My Nikon SMZ-2T is a beautiful scope but the SMZ-U is a step above in terms of resolution, contrast and FOV. I'm curious on a couple points here: First, seems to me that any optical difference between those two scopes would constitute some pretty f...

Yes, arranged similar to the 370, only wider (full 1/4"), and with springs clips to hold the filter(s) securely.

Re: Kohler illumination

I'm curious what the " more nicely made " means? Like I said, I have one of each so it's easy to compare them directly. The Spencer 370 is very nicely made, no doubt, but the Burton has a bit nicer fit and finish. Some of the parts are castings instead of sheet metal, everything is rounded instead ...

Re: Kohler illumination

I agree with Phil, the #370 is more versatile than the #735 by virtue of its elevation capability. I use mine for illuminating other things around the lab quite a lot, including stereomicroscope subjects and micro aquariums for macro photography. I have a Spencer #370, but also this "clone": http://...

What Are These Spencer Eyepieces For?

Seller says he thinks they're for aligning an old Spencer phase contrast scope (Model 15 was the first Spencer offered with phase, I believe). But if that's so, why would they come in a pair?

Re: Kohler illumination

Pretty well put, 75RR. Bottom line is, both do the same thing, but the O-I does it easier. It is limited to orthogonal placement of the scope, however, while the #735 is more flexible but requires more knowledge/futzing to set up. If you're asking about other options, then might say so, although I'm...

Re: AO spencer

Phil, thanks for the comments -- I will always gladly bow to those who know more than me, and enjoy learning. You said: "There is light loss and usually a lowered contrast. Those together can give the impression of a change in crispness." That's what I meant, even if I don't quite know the whys and ...

Re: binocular versus monocular and lighting

Regarding kohler lighting; I wonder if an AO-735 or AO orth-illuminator would be better. Being a true novice it strikes me that, since the 735 is adjustable and aims at the mirror, it might be more useful when tilting the head. It appears the ortho illuminator requires the head and light to be para...

On the other hand, a small bottle of Cargill Type A immersion oil cost $3.85, plus S&H (which probably makes it the better part of a 15 dollar bill), and looks pretty cool sitting there on the shelf, almost as if you know what you're doing, lol. http://www.cargille.com/immeroil.shtml I had a friend ...

Henry, I think it's a particularly nice 'scope you have there, what we AO/Spencer enthusiasts like to call a "black beauty". I don't own one myself, but do have its predecessor, the Spencer Model 13.

Re: Wives and OUR Microscopes

Funny how some folks find it difficult, even impossible, to look through a binocular microscope with both eyes. But I've seen it too. Heck, they breathe a sigh of relief when you tell 'em it's perfectly okay to look through just one eyepiece like a telescope... But here's one for you: can you do the...

Here's a look at a stray Olympus BX45 that followed me home a few months ago.
