<p>[QUOTE=&quot;desertgem, post: 1510524, member: 15199&quot;]The critical measurement on any microscope is not the magnification, but the resolution ( resolving power). RP is how close can 2 lines be to each other and the lens can separate them rather than blurring them into just 1. Each microscope lens, the ocular ( eyepiece) and the objective lens ( close to the object) has a rating that reflects their sharpness and price of course. A poor lens of 20X can be marched with another poor resolving lens of 20X&nbsp; and what you get is 400X larger fuzzy image. It is like taking a 3mp camera image and blowing it up to a 16x20 print., when it should stay at about a 3x5. Take a 12 mp camera and you can have a high resolution 16x20. Most of these USB microscopes have a 3mp or a 5mp sensor ( low). A 12mp usb type of microscope could be very useful @ about 20-30 X max.&nbsp; Lab microscopes above 700X has to use oil between the lens and the object for sharp focus. Around Christmas time, the 1200X microscopes and the 500X Telescopes show up in the toy section, but they are just toys, their resolution is so poor , even though the image is large, the resolution is horrible. You see things that are not there and miss things that are there. Probably drives more people from life science and astronomy than we know. </p><p><br /></p><p>Wait and buy a macro lens for a 12+mp camera or buy a good used&nbsp; binocular &quot;dissecting&quot; type of scope and photograph through an eyepiece with a 8+ mp camera ( even a point and shoot) and you will get the kind of shots you want.</p><p><br /></p><p>And if you have a USB microscope, use a good photo program for best results, and if the LEDs are accessible, use small pieces of black tape to block off some of them to control the light level.IMO.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
