<p>[QUOTE=&quot;desertgem, post: 3739935, member: 15199&quot;]The OMAX is a decent scope for it&#039;s price. It is a pure achromatic lens and maybe on a good day would be useful, but it is for transmission microscopy, not opaque use like the face of a coin. Good on Microorganisms, not on a surface unless you use lights from above and the lens are sharp focus. These are photos I took&nbsp; with my microscope for a discussion about the surface of peace dollars vs. morgan dollars as per toning. The top 2 are at 100X and that is a flat area on a Morgan ( left) and a Peace on the right. The bottom one is a Morgan surface at 400X.&nbsp; At 400X, a coin can not be in focus at all levels.&nbsp; Compare the resolution of glass lens with a USB that adds false pixels to fill the space to make the more magnified photo.</p><p>&nbsp;&nbsp;&nbsp; I could have gone to 1000X, but all above 400 area needs immersion oil to fill the space, and I did not want to add oil to a coin surface.&nbsp;&nbsp; Jim</p><p><br /></p><p>[ATTACH=full]1003067[/ATTACH] </p><p><br /></p><p>[ATTACH=full]1003068[/ATTACH][/QUOTE]</p><p><br /></p>
