WebThis lens has the industry’s highest NA for a 60X water immersion objective lens, maintaining flatness throughout the field of view while showing good correction of chromatic aberration over a wide range of wavelengths. Numerical aperture: 1.27 Super image flatness Chromatic aberration correction: from visible to infrared. WebField of view describes the viewable area that can be imaged by a lens system. This is the portion of the object that fills the camera’s sensor. This can be described by the physical …
WebOct 17, 2024 · Therefore, high NA objectives often have short working distances, which makes it impossible to image an entire non-sectioned brain sample, because the sample … WebHigh-NA metrology architecture Faced with an application to measure a state-of-the-art 60× oil-immersion microscope objective having an NA of 1.49, we realized that the …
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. 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 ...

Ideally, such objectives should be compatible with a wide range of immersion media, which is challenging to achieve with conventional lens-based objective designs. Here we … population medicine bow wyomingWebWhen 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. population media center scholarship
