<p>[QUOTE=&quot;rmpsrpms, post: 3073526, member: 31773&quot;]Here is the coin in a jig I built to show reflectivity. The jig has a V-cut, 45-deg each side. The coin sits on a true grey surface, and other surface is a piece of card stock with black felt pen lines drawn every 2mm. So the lines at the bottom are very close to the coin, while lines at the top are far away (~27mm away). </p><p><br /></p><p>You can see a solid reflection off the close fields, and then a reduced reflection off the far fields, and almost none off the devices.</p><p><br /></p><p><img src="http://i943.photobucket.com/albums/ad273/rparkhurst/46S%20PL2_0_1.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
