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 ... 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 objective has a numerical aperture of 1.0, a field of view of 250 µm, and a working distance of 450 µm. It delivers diffraction-limited performance at λ = 1064 nm.
WebAn objective’s NA is a measure of its ability to gather light. It is an important factor in determining the resolution, depth of focus, and the brightness of images. Objectives with a larger NA gather a wider range of light, resulting in brighter, higher resolution images. WebField of View (mm): 6.63 Focal Length FL (mm): 45.00 ... and excellent image flatness. The high numerical aperture (NA) allows for excellent light collection efficiency to better capture faint signals, enabling a shorter …
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 placed close to the specimen with which it must … WebMaximizing the on-sample field of view in fluorescence microscopy is of increasing relevance across a wide range of applications, including high content screening of large …
