<p>[QUOTE="rmpsrpms, post: 2304576, member: 31773"]For digital microscopes, the "magnification" includes the ratio of the screen size to the sensor size in addition to the optical magnification. The optical mag on that image is about 2x, while the ratio of screen size to sensor size is about 30x, so the microscope would report a magnification of perhaps 60x for the image. A 250x magnification would then be more like 8x optical, which would zoom nicely in to see a good magnified view of the mintmark.[/QUOTE]</p><p><br /></p>
