Optical resolution
WebJan 19, 2024 · The resolution of an optical microscope is not solely dependent on the NA of an objective, but the NA of the whole system, taking into account the NA of the microscope condenser. More image detail will be resolved in a microscope system in which all of the optical components are correctly aligned, have a relatively high NA value and are working ... WebOptical resolution is usually defined as the ability to distinguish two objects which are close together, which is difficult due to the overlap of the Airy disks. Common criteria for the …
