Megapixel is how we measure resolution, another term for resolution is size. For example a camera that takes a photo that measures 640x480 would be .3 megapixels, a photo that measures 1280x1024 would be 1.3 megapixels.</p><p><br /></p><p><font size="4"><b>Comparing optical magnification in traditional and digital devices</b></font></p><p><font size="3"><b>Example 1: Magnification vs field of view in traditional and digital microscopes</b></font></p><p>The magnification value provided for Dino-Lite microscopes is intended to be useful as a reference to comparable magnification using a traditional microscope but may differ in some cases. A more useful measurement when comparing a digital microscope and a traditional microscope is the field of view (FOV) under a given magnification. This number represents a real dimension and does not change based on variations of monitor size, pixel dimensions, or resizing the software window.</p><p><br /></p><p><img src="http://dinolite.us/media/images/compare2.png" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>In the image above a sample of the views from a compound microscope and a Dino-Lite are compared. Under this particular setup, the field of view at 40x with the compound microscope was approximately the same as the field of view using the Dino-Lite at 65x. <b>Switching the Dino-Lite display in the software to full screen causes the image to appear larger or more magnified (digital zoom), but the field of view remains the same.</b></p><p><br /></p><p><font size="3"><b>Example 2: Determining actual magnification in digital microscope devices</b></font></p><p>Due to the differences explained above, it is often more useful to compare field of view rather than magnification. If you have a requirement that you must work at a particular magnification level, you can compare the physical dimensions of the original item being magnified to the resulting size of the item on your display. For example, if the actual dimension of your item is 10mm you can compare that to the size of the item when displayed on your screen in the Dino-Lite software. Adjust the magnification on the Dino-Lite until the item occupies 100mm on your screen for an overall magnification of 10x.</p><p><br /></p><p><img src="http://media.dinolite.us/media/catalog/product/h/o/how-to-10x.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><br /></p><p>Magnification is relative to the working distance.</p><p><img src="http://media.dinolite.us/media/catalog/product/w/d/wd_03_1.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
