WebOptical magnification is the ratio between the apparent size of an object (or its size in an image) and its true size, and thus it is a dimensionless number. Optical magnification is sometimes referred to as "power" (for example "10× power"), although this can lead to confusion with optical power. Linear or Transverse magnification[edit] WebJan 1, 2016 · High-numerical aperture (NA) optical objective lenses are widely used in high-spatial-resolution optical imaging and fabrication techniques. In optical microscopy, these high-NA objectives produce tightly focused optical fields as probes to interrogate the sample properties within the focal volume and generate the contrast for imaging. fis hacked
