2013-06-17 · Numerical techniques are used to enhance the computational efficiency of each subsystem. A distinct merit of the proposed model is that it can be used to simulate imaging results for diverse setups of the scanning microscope, like various polarizations, numerical aperture, and different detector pinhole sizes.

doi: 10.1364/AO.32.005689. 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 numerical aperture s1.65d objective lens are investigated by a scanning near-field optical microscope. 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.

Figure 1 illustrates a series of light cones derived from objectives of varying focal length and numerical aperture. Numerical aperture (NA) is defined as being equal to n sin θ, where n is the refractive index of the medium between the objective lens and the object (n≅1 for air) and θ is half the angular aperture (or acceptance angle of image-forming rays) of the objective lens (Jenkins and White 1957). The 0.25 is the Numerical Aperture. The 160 is a standard DIN measurement in millimeters of the tube length of the microscope required for this lens to work properly. Finally, the 0.17 is the thickness in mm of the cover slip that you should use. 0.17mm cover slips correspond to a number 1 cover slip. Numerical aperture is an important concept in understanding how light microscopes resolve images and how you can avoid empty magnification.

2021-3-26 · If you are looking at the input to the lens from a scanning mirror, then you may use the scan angle of 7.5deg to determine a numerical aperture but this will be beam diameter dependent. At the image side, you could use the effective focal and the ideal collimated beam diameter (or pupil size) of 4mm to estimate a numerical aperture.

16 Mar 2020 A scanning objective lens provides the lowest magnification power of all However, the numerical aperture (an indication of resolving power of  The Numerical Aperture (NA) of the objective equals the sine of the half-angle ( theta divided by two where theta is the entire angle). For a low power 4x system, the  is numerical aperture, which is a measure of a lens's ability to gather light. The higher the The scanning objective magnifies the image to four times the original  1 Jul 2020 design of mesoscopic scanning OPM to allow using low numerical aperture (NA) objective lens.

Numerical Aperture. Numerical aperture (NA) is defined as being equal to n sin θ, where n is the refractive index of the medium between the objective lens and the object (n≅1 for air) and θ is half the angular aperture (or acceptance angle of image-forming rays) of the objective lens …
