Re: Does Anybody Recognize this Inverted 'Scope?

Is there anywhere that looks like a location that might have housed a ground glass filter? Maybe got damaged or thought to be precious, like the missing sliders. Not that I can see. The condenser assembly was intact and in pretty nice shape when I received it. I believe that once I get the specimen...

Re: Does Anybody Recognize this Inverted 'Scope?

The rings are just painted grooves around the post that holds the condenser. When the objective with the yellow marker ring is used, I merely slide the condenser assembly to the position of the yellow ring on the post; same for the objective with the green marker ring. I move the condenser assembly ...

Re: Does Anybody Recognize this Inverted 'Scope?

How far is the iris from the condenser front lens ( the one on top) and and are there any lenses between the iris and filament? The setup is as follows: Bulb Centering Mechanism Lens Filter slot IRIS Slider slot (0.7" x 2-7/16") Lens (lens closest to specimen) Distance from the iris to the lens clo...

Re: Does Anybody Recognize this Inverted 'Scope?

Well, I tried Kohler and was totaly unsuccessful. Let me explain. On the illumination post there are two colored rings, one yellow and one green. These, I assume, correspond to the colored rings on the objectives, so when the objective with the corresponding colored ring is used, I set the illuminat...

Re: Does Anybody Recognize this Inverted 'Scope?

See if you can adjust it for Köhler and see what happens. At least you know how to get a filament image so you can center it. It's not possibly the partially closed condenser iris in focus, is it? There isn't a condenser iris as in a standard microscope, but if you look at the last picture in my fi...

Re: Does Anybody Recognize this Inverted 'Scope?

Is the vignetted field perfectly uniform ? does it have a fuzzy or sharply defined border? The condenser should be focusable for Köhler, which should defocus the filament image. The sliders are just to obtain phase, otherwise you should be able to to fo BF o.k. I came across a parts head and eyepie...

Re: Does Anybody Recognize this Inverted 'Scope?

A couple of questions. The binocular head had a bad mirror, which I replaced. When looking through either eyepiece either singularly or together, there is a a bright center section and a darker perimeter. Will the "sliders" somehow take care of this. The bright center section is about 2/3 the field ...

You might find it easier to find a 15X eyepiece to get 645X, 150X, and 75X from your 'scope. I believe the 147 and 184 eyepieces are 15X
