Други <p>The 10x eyepiece is suitable for <strong>all microscopes with 23.2mm eyepiece tube diameter</strong>. This diameter is widely used in stereo microscopes, also from other brands or manufacturers. Please select the <strong>eyepiece magnification in correspondence to the objective</strong> you are using. A low objective magnification allows for a higher magnification of the eyepiece. For example, combined with 4x or 10x objectives, eyepieces with 20x or 25x magnification can be used without loss of image quality. With a 100x objective, a 10x or 12.5x eyepiece is usually the highest recommended eyepiece magnification.</p>
<p>To calculate the <strong>maximum useful magnification</strong>, consider the numerical aperture (N. A.) of the objective lens:</p>
<p>numerical aperture of the objective lens x 1000 = max. useful magnification</p>
<p>Here is a typical example: for a 10x objective with numerical aperture NA 0.25, a maximum of 250x magnification can be realized. This is realized with a 25x eyepiece. The numerical aperture is usually printed besides the magnification factor on many objectives.</p>
<p>Magnifications beyond the max. useful magnification do not show any further details (so-called <strong>“empty magnification”</strong>) and are therefore not recommended.</p>
