WebMay 1, 2024 · With the characteristic that there is a relatively small depth of field (DOF) for a microscope at high magnification (50×), a series of SSD images are captured along with the microscope focusing at different depths under the surface by means of micro-focusing control. The definition of each image is calculated through wavelet transformation. WebMagnification The number of times larger an object appears compared to the size of the original object. Resolution The ability to distinguish 2 points as distinct from one another. Light Microscopy Uses focused light and lenses to magnify specimen. Samples are thinly sliced and generally dead.

WebThe magnification of a lens is shown by a multiplication sign followed by the amount the lens magnifies. So a lens magnifying ten times would be ×10. The total magnification of a microscope is:... WebResolution. Resolution is the ability to distinguish between two separate points. If two separate points cannot be resolved, they will be observed as one point. The resolution of a light microscope is limited by the wavelength of light. As light passes through the specimen, it will be diffracted. The longer the wavelength of light, the more it ...
