High na objective field of view

WebThe ideal point spread function ( PSF) is the three-dimensional diffraction pattern of light emitted from an infinitely small point source in the specimen and transmitted to the image plane through a high numerical aperture ( NA) objective. It is considered to be the fundamental unit of an image in theoretical models of image formation. 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 …
