WebJul 12, 2024 · The NA of an objective is an important aspect and relates to the image resolution. In brief, the resolution is the ability of the objective to distinguish details in your specimen. Without a correspondingly high NA, an objective with a high magnification would be unable to resolve sample detail. WebObjectives are designed to image specimens either with air or a medium of higher refractive index between the front lens and the specimen. The field of view is often quite limited, and the front lens element of the objective is … population of slovakia 2020

WebThe miniature objective is 7 mm in outer diameter and 21 mm in length (from object to image). It is used in a fiber confocal reflectance microscope. The miniature microscope … WebJul 28, 2024 · An objective lens with a low numerical aperture (NA) has a large field of view but poor resolution. In contrast, a high NA objective lens will have a higher resolution but reduced field of view. In an effort to close the gap between these trade-offs, we introduce an acoustofluidic scanning nanoscope (AS-nanoscope) that can simultaneously ...
