The highest numerical apertures achievable with dry objectives, operated with air between the objective and the object, are approximately 0.95. Substantially higher values of e.g. 1.5 or even higher can be achieved with immersion objectives , where the gap between the object and the objective is filled with a liquid – water or some immersion oil with a higher refractive index , often

Vohnsen, “Polarization structuring for focal volume shaping in high-resolution microscopy,” Opt High-numerical-aperture lens-free on-chip imaging using synthetic aperture A new lens-free on-chip microscope, which adopts a synthetic aperture approach, achieves a half-pitch resolution of 250nm with an effective numerical aperture of ∼1.4 and a wide field of view (over 20mm2). 2021-03-15 · The exceptionally high numerical aperture of the meta-lens enhanced fibre and its capability to optically trap objects with a single meta-fibre device enables one to envision applications in areas Cylindrical-vector beams are of increasing recent interest for their role in novel laser resonators and their applications to electron acceleration and scanning microscopy. In this paper, we calculate cylindrical-vector fields, near the focal region of an aplanatic lens, and briefly discuss some app … 80% of its region overlapped (in one dimension) with its adjacent one, and the scanning covers a Fourier spectrum range equaling a numerical aperture of NA syn = 0:36, which is within the NA of the 20X 0.4NA objective lens. 20 images are captured in transmissive mode, and the phase retrieval algorithm is used to reconstruct an image.

In optical engineering, the objective is the optical element that gathers light from the object being observed and focuses the light rays to produce a real image. Objectives can be a single lens or mirror, or combinations of several optic 4 Nov 2016 Additionally, we demonstrate the application of a tapered optical fiber tip, as used in scanning near-field optical microscopy, to measure the point Numerical Aperture (N.A.): This is a number that expresses the ability of a lens to resolve fine detail in an object being observed. It is derived by a mathematical Numerical aperture, or N.A., is a value that indicates the resolving power of a lens and is defined by the equation below. n: refractive index of observation The numerical aperture (N.A.) is usually engraved on the side of the condenser lens.

Each of these two methods has its limitation. The SELFOC lens' numerical aperture (NA) is low, which limits its light-collection efficiency. A 1:1 lenslet array can have a high NA, but its resolution along the scanning direction is low, which means it is not suitable for 2-D scanning. In this paper, line scan optics with a high NA will be

The pure focused evanescent ﬁeld is mapped and a splitting phenomenon of the focal spot along the direction of polarization, caused by depolarization, is observed not only on the In order to scan a line, the scanning optics usually employs either NSG's SELFOC lens or a 1:1 lenslet array. Each of these two methods has its limitation.

Each of these two methods has its limitation. The SELFOC lens' numerical aperture (NA) is low, which limits its light-collection efficiency. A 1:1 lenslet array can have a high NA, but its resolution along the scanning direction is low, which means it is not suitable for 2-D scanning What you are probably speaking of here is the "numerical aperture", an indicator of the microscope lens property that is rather equivalent to the "exposure impact" of a camera lens. A certain numerical aperture of a microscope objective generally corresponds to a certain f/number, although there are some complications. However, the numerical aperture (an indication of resolving power of an objective) of a 100x dry objective is much lower than that of a 100x oil immersion objective and, as a result, the ability of the lens to resolve fine details in the specimen is much lower, too. Immersion Media and Objective Lenses high-numerical-aperture lenses: standing-wave scanning uorescence microscopy Stanley S. Hong, Michael S. Mermelstein, Berthold K. P. Horn, and Dennis M. Freeman December 11, 2004 Abstract We propose and demonstrate a new type of far- eld uorescence microscope capable of sub- resolution without high numerical aperture (NA) lenses.
