Define magnification and field of view
WebAnother choice for the same magnification would be a 10X eyepiece with a 25X objective. Because the 25X objective has a higher numerical aperture (about 0.65 NA) than the 10X objective (about 0.25 NA) and numerical aperture values define an objective's resolution, the latter choice is ideal. If photomicrographs of the same viewfield were made ... WebThe field number of typical eyepieces varies between 6 and 28 millimeters and (in general) decreases with the magnification of the eyepiece. For example, an eyepiece having a …

WebMicroscope Lab Activity Introduction "Micro" refers to tiny, and "scope" refers to view or look at. Microscopes are tools used to enlarge images of small objects so they can be studied. The compound light microscope is an instrument containing two lenses, which magnify, and a variety of knobs to resolve (focus) the picture. Because it uses more than one lens, it is …

Focal length is the distance between the optical center of the lens, and the camera sensor or film plane when focused at infinity. The optical center is where light rays converge inside the body of your lens. The focal length defines the magnification and field of view for a given lens.
