Microscope for viewing grain size

I suppose this is a bit off topic, but I'm looking for a microscope (preferably under 50-100 dollars) that I can put a piece of steel under and view at 100x magnification to view grain size and structure.

The problem is I don't want to buy one online that I haven't seen in person because A. it could be of very low quality and B. its possible a knife wouldn't fit under there.

So could someone with a microscope recommend one?

Thanks all!
 
You might get an idea of what's needed at www.buehler.com They handle Nikon microscopes .These are of course metallurgical microscopes as apposed to biological microscopes . For $100 you could only get a used one.
 
That's a pretty tall order unless you're EXTREMELY lucky at a garage sale. A microscope that will truly resolve at 100x magnification will likely cost quite a bit more than that, especially if you want a stereo view so that yuo can have depth of field to the image. I've seen some in tool catalogues for around $350.00 that look good on paper but they're off brands I have no experience with.

Your location isn't noted in your profile. Where are you located?
 
Used ones only, for that price.

Drop by the State/County/City surplus in your area. Schools and hospitals get "rid" of there "old" stuff and you can find some incredibly new items.
 
Interesting link Mete. I was way off track in what I was thinking. Those are interesting mics. I think one of my wife's mics has a brightfield function, but is the more traditional configuration.

Cool stuff. I love good optics!
 
Maximus, the magnifier shown ,60-100x ???? that type that I've used was far less than 60x.[I don't buy from Radio Shack too many problems for me and others I know !!].....Blue Sky, the microscopes shown are all BIOLOGICAL microscopes where the light goes through the translucent or transparent sample . The metallurgical microscope has a mirror system since metals are opaque not transparent !!!

Radio Shack typically uses area magnification because it produces more impressive numbers than liner magnification which is what everyone thinks you are talking about when you say magnification, i.e. it makes a mm look like a cm which is 10 times the length, of course this also makes a square mm look like a square cm which is 100 times the area.

Yes of course, I should have caught that.:o Thanks mete.

I have the little Radio Shack model. I don't know what the actual magnification is, but you can see the grain structure.

It's not Swarovski, but for $8 its a neat little gadget.
