It is a very, very early vertometer or, what today, we call a lensometer. When you purchase new glasses, this is the device that finds the center of a lense blank as well as verifying the power of the blank. You could also use this to measure the strength of your glasses. Today, most modern lens/gla...

Several thoughts - as far as matching the enamel, utilize the paint matching computer at the paint center in the big box home improvement stores or an actual paint store. They need a flat sample area that's usually at least the size of your pinky fingernail. The problem is always matching the sheen ...

Let's try and find an Oboe... that way we can start fine tuning!!! And just a reminder, A=440 doesn't have anything to do with angstroms, fortunately, probably no electron microscopists lurking around here!

Gorgeous!

OY! The AO 569 Stereostar arrived but with frustration... I've almost universally begun to send a PM to Ebay sellers I buy microscope components from... "THANK YOU, in advance, for carefully packing my microscope.... " in this particular case, I advised the seller I was purchasing the setup especial...

hello again, Scarodactyl... here's a link to the manual for that particular refractometer, the Bausch and Lomb Abbe 3L...

I hope it gives you a more thorough explanation as to suiting your application:

Hello Scarodactyl! Most refractometers are intended to measure the angle of refraction of liquids, however these B&L units are more of a research instrument and can be used to measure index in even, uniform opaque materials. For use in my hobby microscopy lab, this is clearly over-kill. When I was i...

Hey MicroBob and apochronaut! I'm getting ready to experiment in the milling machine with a Bridgeport boring head. By setting up the right offset on the mill, it's possible to cut somewhere near 7" diameter circles. The idea is to replace the milling cutter with a carbide scribe point and then, aft...

Well, as a follow-up to my frustration with finding an actual AO glass stage plate, on Fleabay, it was cheaper to purchase this entire setup (see auction listing pic) just to get the stage plate than to keep hunting for the plate alone! I'm currently starting to search for a lens edger in order to s...

Hello again, Hobbyst46! I stand corrected and learn something new everyday! I so closely associate the sodium light source as an emission source comparison, I've just got that in my head as the only scenario. I think I have that Cargille publication and this is another one that makes for interesting...

... additionally, if you find a Leitz trinocular tube for the SM, make sure it has the camera adapter (shown) - if it doesn't, PM me and I'll sell you one for $10 + shipping. You have a sweet setup there!

MichaelG. posted an excellent reference. Personally, on the SM lux, I would recommend the FS tube for a couple of reasons: A). You already have the eyepiece/prism arrangement that allows you to directly view the image the camera is receiving**; and, B). The trinocular arrangement will remove any str...

I have one of these (refer to link) - As you can see, they're dirt cheap BUT, in this case, the shipping exceeds the cost of the surface plate!! Mine suffered a little damage to one of the corners because UPS ground freight was a little aggressive in handling it. I actually use mine for metrology re...

Hello Hobbyst46! THANK YOU for the compliment! These refractometers differ (in application) from what you describe in that they measure how an unknown sample influences the angle of refraction of white (visible) light entering the sample. An example would be the common bottle of Cargille immersion o...

I love that you posted this! In college, I worked for a microbiologist, James F. Wilson, who had a DeFonbrunne micro-injection apparatus mounted on a marble analytical balance table. When Wilson retired and had to move to a smaller lab, I had to dismantle the table that weighed in at about 400 lbs. ...

Hello Kurt! Thank you for the good thoughts during our recent storm. Burlington is in the middle of the state and we, literally, pretty much dodged most of the storm. I had a little water seep into the machine shop under the door since the shop is at ground level, but other than that, made it throug...

It was the best of times, it was the worst of times... it was the epic of belief, it was the epic of incredulity... Well, probably 10 years ago, I bought this beautiful old Bausch and Lomb refractometer from Duke University. Back then, I began taking it apart out in the repair shop in order to clean...

I apprenticed for 4 years with a master machinist, Klaus Wirbelauer WOW ! That's a name from the past. I visited with Klaus on many an occasion, back in the day. He was very kind and generous until you (I) asked a really stupid question. lorez *that* is wonderful! Tell me more about it - are you in...

You actually solved that mystery before I did, MichaelG! I hadn't thought about that monogram in years!

Actually, the third component of the stage monogram is G (as OP pointed out)... this stage was manufactured by Gebruder Marzhauser... "the brothers Marzhauser." Leitz and several German manufacturers did not make their own mechanical stages but farmed it out, in this case to "the Brothers Marzhauser...

The finish on that pol stage is gorgeous - looks virtually unused!

That's amazing tape! I want to say I've seen it used as a shipping barrier in a remote control to prevent dry cell batteries from working - there was a little tab to be removed (by the consumer) between the battery and the terminal in the device.

I apprenticed for 4 years with a master machinist, Klaus Wirbelauer, in the microscope department at Carolina Biological Supply Company and this is one of my favorite tricks that he taught me for removing asset tags from painted finishes. It works like nobody's business but you've got to use a bit o...

Absolutely, MichaelG! My plans for this setup are to leave it completely intact as I got it - more or less a museum exhibit. I love those periplan eyepieces but I've got other sets so I'm gonna honor this rig as it was used. I've got to find a Leitz light meter/photoelectric cell that should be on t...

THANK YOU so much for your help with this! I figured, when I looked at the beefy-ness of that illuminator housing, there was probably a heat sink or something in there that made it different from the standard Stereo Star illuminator... I have should have suspected a halogen source! There's currently...

This is a pic of the very crudely modified y axis knob of the Ortholux. It was done by such primitive means, they even used a spur gear as a spacer between the top of the Leitz knob and the stage interface.

So, in a previous post, I highlighted this weird Leitz riser platform I bought from Penn State Surplus property. Because they're not in the shipping business, I had a connection who picked this thing up Labor Day weekend and just delivered it to my hands on Thursday. It had some original paperwork w...

*THAT* is one groovy setup. So I'm assuming that cup on the end of the horizontal photo-tube is 1/2 of a light baffle?

I am all set, thanks for the offer.

Hey Jim!

I may be interested in that series 10 trinocular head... I've got my eye on a phase contrast setup that includes one with it but will definitely PM you if that falls through!

So here's the newest member of my AO clan - the Stereo Star 580. I must say, I LOVE THIS THING! It's built like a tank and has that wonderful camera mount. I've been wanting to add the camera mount to my Zeiss OPMI 6S and for what it typically costs on Fleabay for that adapter, I could buy about 5 o...
