Hi,

 

I bought a second hand microscope off our local classifieds. It got it for 70 Dollars, as the only buyer. The seller inherited it from his father, and it had been standing in a corner, collecting dust. It's impossible to find any information about the brand itself. It is likely from somewhere between 1950 and 1990 since accessories are marked "west germany". When I got it, the focuser knob was stuck and I had to take the whole thing apart to get to it. It was a bit nerve-wrecking at one point with ball bearings jumping all over the table. I got to the focususer and a few dashes of WD-40 did the trick, and it is now fully operational. 

 

It has a nice feature set; binocular head with 10x eye pieces, 3 Wetzlar objectives (one oil), mechanical stage, removable and adjustable condenser, diaphragm, and filter holder between the lamp and diaphragm. A white diffuser filter was incuded. The whole thing is metal. Not a plastic piece in sight.

 

The focuser is interesting in itself in the sense that I can move it carefully and it works in "slow motion" mode, but when I move it faster, it switches to coarse adjustment. Did anyone see something like that before?

 

Can anyone shed some light on what kind of microscope this could be, and why there is almost no reference to the brand?

Good purchase.  One of my monocular microscopes is an Optikon with Wetzlar optical train.  It is a very heavy scope, smooth operating.  Everything on the scope referring country of manufacturing states "Germany", no West or East.  So, I am supposing it was made pre-World War II.

Looks to be a very nice find. If you really want to learn more about it you might consider posting on a forum that's devoted to microscopy. I hate referring folks away from here, and wish this forum were more alive, but "it is what it is" as the threadbare saying goes.

Well... I'm rather knowledgeable on European continental microscope manufacturers, but the brand "Steinmar Berlin" doesn't ring a bell at all...

"Steindorff Berlin"? Yes, but that's an entiraly different matter. This microscope isn't a Steindorff.

Judging from the pictures, I would say it's kind of a "Frankenstein scope". Doesn't mean it's junk!!!

The foot looks to be an older PZO-STUDAR foot, but I won't go any further without having access to the thing itself.

""Wetzlar" is a city/region only, often used to make an impression as being high quality. As in: "Wetzlar ~high quality optics", "Solingen ~high quality knives".
