Scanning power objective magnification
WebMagnification is a very simple concept, but it sometimes can create confusion because of its own definition. The aim of this blog is to clarify magnification in scanning electron microscopes (SEM) and focus on other parameters which can describe better how big an object is represented.. The first magnifying glasses date back to the Greeks, with … WebSlowly rotate the low power (10X) objective into position. Look through the oculars: Sharpen the focus, if necessary, with the coarse adjustment knob. Only a minimal amount of adjustment is usually necessary. Center the specimen in field, if necessary. Look at the microscope from the side: Rotate the high power objective into place very carefully!
