Re: New microscope! AO Stereostar 570

Nice find! The 570 is a beautiful scope and it works great. That 1.5x aux is a bit rare, so that's a good bonus. I have a 0.5x on hand at the moment, but your current stand will not work with it iirc. At the very highest extension the glass stage will almost be in focus. The accessories list/manual...

Re: New microscope! AO Stereostar 570

Scarodactyl -- Ahh gotcha, most of my samples will be pretty large height wise so if it's already close to my max height adjustment it almost certainly wouldn't be practical for me, is that just the specific one you have or is that all of the 0.5x aux lenses?

New microscope! AO Stereostar 570

I've been looking for a stereo scope for a few months and just managed to snag this for about $100 shipped The optics look fantastic, the light is not great but it definitely gets the job done. It came with a 1.5x aux lens which I hadn't even noticed in the original pictures, eventually I would like...

geo_man,

Calcite thin section

Just finished this calcite thin section, it's a fairly soft mineral so it was easy to make at home with sandpaper, I will probably make a new one soon and switch from coarse grit to a finer grit to prevent having the scratches visible in the final product. I am not sure what this pattern is called i...

Hey everyone, I am moving to a new apartment and that has spurred me to go through my rocks and minerals, instead of throwing anything out I figured I'd offer them up here.

Re: Granite thin section

PeteM, My first one took many many hours, I broke a few slides and had to start all over more times than I'd like to admit. With just the bare essentials it depends greatly on the general hardness of your sample, I had a jasper conglomerate that took me nearly 4 hours of hand griding. A thin section...

Re: Granite thin section

Thanks!

In one of my field books there are instructions for making a DIY/portable polarizing microscope with a hand lens and polarizing film.

It's just generally not useful to use a polarizing scope on hand sample(for rocks, I have no idea about biology) so I have never bothered.

Re: 3.2x Objective wont focus

Sorry for the delay in responding, I had a 24 hour shift at work. My objective has at least two lenses, (the rear one may be a filter for polarization?) Assuming the objective is a 37mm parfocal lense I would expect it to focus approximately 37mm from the turret, 8mm shorter than my other objectives...

Re: 3.2x Objective wont focus

MichaelG., I had just assumed the plezy would be necessary because of the age/style of the objective being the same as my 100x. MicroBob, I must have misinterpreted what you had said, I also thought that it would have meant that I would have needed the 3.2x closer instead of further away. Is it poss...

Re: 3.2x Objective wont focus

4cm, maybe even 5, it is a very very long way from being equal with the rest.

I can try and get measurements when i get home.

I just can't think of what it could be let alone how to fix it(aside from getting a new objective) but I would certainly prefer for that to be a last resort.

Re: 3.2x Objective wont focus

My 100x is 37mm but has a plezy to bring it to 45mm like the other objectives

The 3.2x will focus without the plezy about 40mm higher than the other objectives

Re: 3.2x Objective wont focus

The last two types can be used together: - on a 160mm tube with 10mm eypiece pickup point eyepieces or: -on a 170mm tube with 18mm eypiece pickup point eyepieces. Can you leave the plezy away under your 3,2;1 objective? Bob I am pretty sure the two objectives I have with the double knurl are 37mm w...

Is gumming up of the oil condensers fairly common?

Is this a procedure that would be worthwhile being familiar with if I can on working with an oil condenser?

Hey 75RR,

I think that would probably fit
I would prefer the 553082 (nicer looking and had beveled interior edges to avoid bumping objectives) but I am interested depending on asking price, feel free to PM if you would prefer to talk there.

Re: WTB: Leitz mechanical stage for polarizing stage #40, #42 Part Number 553082

microb,

I have a Leitz SM-LUX-POL, my stage has two bolts in the rear but I would have to pull it off to get a decent picture or to measure and see if it would fit with that one.

I'll have to check!

Edit:
The mounting holes on mine are about 48mm center to center
