For example, at 10x magnification 20mm might fill your field of view, whereas at 40x magnification you might only see 5mm. Going to high power on a microscope decreases the area of the field of view. At 1000x magnification you will be able to see 0.180mm, or 180 microns. 0000018898 00000 n 0000014239 00000 n Below is a list of your field of view at different magnifications. 0000045837 00000 n 0000019699 00000 n To determine the total magnification used with a 40x objective, we simply multiply the 10x by the 40x to get a total magnification of 400 times under a 40x objective. At 1000x magnification you will be able to see these same items, but you will be able to see them even closer up.
