Na of a 20x lens
Witryna23 kwi 2024 · These lenses combine high numerical apertures (NAs) with large fields-of-view (FOV). The use of silicone oil *1 for liquid immersion observation *2 enables ultimate clarity when imaging live, thick specimens. WitrynaFor example, a 20x objective and a 100x objective, both of which contain a phase plate near the diffraction plane (rear focal plane), will require condenser annuli having different diameters that correspond to the objective magnification and numerical aperture.
