<p>[QUOTE=&quot;desertgem, post: 1563361, member: 15199&quot;]Again, as I know many are confused about this, magnification ( X) is not a specific measurement of ability , RESOLUTION and/or Numerical aperature is. Resolution is the distance between 2 lines that can be separated as 2 separate lines rather than one blurred line. A blur magnified 400 times is just a big blur. With a digital microscope, some of the resolution is with the lens, and most is with the sensor. Plastic lens are not very good, so some resolution goes down the drain. They are cheap however, ground glass lens are many times more expensive, Corrected glass lens are even more expensive.</p><p><br /></p><p>Even a glass lens with a sensor of&nbsp; 5 mp will only have that resolving ability, 5mp.&nbsp; So much of the magnification given in an advertisement is software cropping and then enlargement so the result may look &quot;greatly magnified, the ability to see lines or small details , doesn&#039;t really improve. </p><p><br /></p><p>They are inexpensive and they do provide what some may be satisfied with, but don&#039;t use magnification as a key measurement, use mp.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
