I was speaking USB scopes, not stereoscopes, but a similar statement goes for the objective magnification in a stereoscope. Indeed you don&#039;t need much more than 3-5x in a stereoscope objective. Coupled with 10x eyepieces, this yields from 30-50x, which is I think where you were going.</span></p><p><span style="color: #000000"><br /></span></p><p><span style="color: #000000"><br /></span></p><p><span style="color: #000000"><br /></span></p><p><span style="color: #000000">I&#039;m still talking optical magnification of the USB scopes. They really are as low as I&#039;m saying, with the additional magnification happening mechanically and digitally, but NOT optically. </span></p><p><span style="color: #000000"><br /></span></p><p><span style="color: #000000"><span style="color: #000000"><br /></span></span></p><p><span style="color: #000000"><span style="color: #000000"><br /></span></span></p><p><span style="color: #000000"><br /></span></p><p><span style="color: #000000">The &quot;pod&quot; is the main body of the scope, not including stand, eyepieces, etc. The SZ7 pod magnification is 1x-7x.</span></p><p><span style="color: #000000"><br /></span></p><p><span style="color: #000000"><span style="color: #000000"><br /></span></span></p><p><span style="color: #000000"><span style="color: #000000"><br /></span></span></p><p><span style="color: #000000"><br /></span></p><p><span style="color: #000000">Interestingly though, a few USB scopes can focus nearly to infinity, so it is possible that a USB scope that is touted as having mag range from 1x...500x may really have that capability. The &quot;mechanical magnification&quot; from a 2.6um pixel pitch sensor to a 260um pixel pitch monitor is 100x. If indeed the marketing folks were targeting such a monitor, then the scope would have maximum optical magnification of 5x, and minimum magnification of 0.01x, ie close to infinity. This is indeed possible, though I expect a good portion of the magnification quoted is actually digital. Let&#039;s say the digital zoom is 5x. This means the actual mag range is .01x to 1x, which is easily achieved. </span>[/QUOTE]</p><p><br /></p>
