<p>[QUOTE=&quot;desertgem, post: 2882507, member: 15199&quot;]Don&#039;t want to confuse the issue that Fred and Books brought up , as I agree with it.</p><p><br /></p><p>BUT, if you actually ever get the use of a SCANNING Electron microscope, Coin varieties would be one big area of my use. I took several classes in SEMs in the 70s when they were relatively new and I was use to using the TEM ( which has higher resolution, but basically useless on surface structures. Back then they were barely available inthe lab. Today most universities have SEM labs, especially for study of surface antigens on cells and viruses and microorganisms. They are &quot;almost&quot; as easy to use as light microscopes, but very high resolution and being digitally integrated can magnify from 10X -60,000X or higher with great depth of field than light microscopes. They can stack images and if tilting the stage produce 3-D images of huge size. Expense of course limits wide usage in coins and such, but if someone buys me one, I will take a few years off the forum and play.... Not a B/S/T offer <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p><a href="https://www.nikonmetrology.com/en-us/product/jcm-6000-plus-neoscope" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.nikonmetrology.com/en-us/product/jcm-6000-plus-neoscope" rel="nofollow">https://www.nikonmetrology.com/en-us/product/jcm-6000-plus-neoscope</a>[/QUOTE]</p><p><br /></p>
