They offer excellent … 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 ...

WebWhen using higher magnification objectives, field of view is being restricted for no reason. By using lower magnification objectives, changing from a 100x, 1.30 NA objective to a 40x, 1.30 NA objective, field of view is increased by 450%. That represents a 450% increase in sample area with no loss in resolution.
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. dallas county greenWebnews presenter, entertainment 2.9K views, 17 likes, 16 loves, 62 comments, 6 shares, Facebook Watch Videos from GBN Grenada Broadcasting Network: GBN... birchall auto electricalWebJun 20, 2016 · However, high NA objective, large exposure field of view (26mm×1.5∼2mm), and strict lithography performance are severely restricted or conflict with each other, which makes the optical design ... dallas county government jobsWebField of View (mm): 6.63 Focal Length FL (mm): 45.00 ... and excellent image flatness.
