Highest numerical aperture lens
WebSystem Throughput, f/#, and Numerical Aperture. This is Section 2.1 of the Imaging Resource Guide. The f/# (pronounced “F-number”) setting on a lens controls overall light throughput, depth of field (DOF), and the ability to produce contrast at a given resolution. Fundamentally, f/# is the ratio of the focal length, (f) ( f) , of the lens ... WebFor 20X magnification, which can be a numerical aperture of 0.6 to 0.8, the depth of field drops to about plus or minus 500 nanometers. Moving into high magnification with oil immersion at a numerical aperture of 1.47, the depth of field drops very dramatically, And the depth of field could be plus or minus 0.1 to 0.2 microns (100 – 200 nm).

Webwhere n is the refractive index of the imaging medium between the front lens of the objective and the specimen cover glass, a value that ranges from 1.00 for air to 1.51 for specialized immersion oils. Many authors … WebHigher values of numerical aperture allow increasingly oblique rays to enter the objective front lens, producing a more highly resolved image. This interactive tutorial …
In most areas of optics, and especially in microscopy, the numerical aperture of an optical system such as an objective lens is defined by $${\displaystyle \mathrm {NA} =n\sin \theta ,}$$ where n is the index of refraction of the medium in which the lens is working (1.00 for air, 1.33 for pure water, and typically 1.52 for … Ver mais In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes the range of angles over which the system can accept or emit light. By incorporating index of refraction in its definition, NA has … Ver mais A multi-mode optical fiber will only propagate light that enters the fiber within a certain range of angles, known as the acceptance cone of the fiber. The half-angle of this cone is … Ver mais • "Microscope Objectives: Numerical Aperture and Resolution" by Mortimer Abramowitz and Michael W. Davidson, Molecular Expressions: Optical Microscopy Primer … Ver mais In laser physics, numerical aperture is defined slightly differently. Laser beams spread out as they propagate, but slowly. Far away from the narrowest part of the beam, the spread is roughly linear with distance—the laser beam forms a cone of light in the "far field". … Ver mais • f-number • Launch numerical aperture • Guided ray, optic fibre context • Acceptance angle (solar concentrator), further context Ver mais http://zeiss-campus.magnet.fsu.edu/tutorials/basics/numericalaperturelightcones/index.html
The ability to resolve features in optical lithography is directly related to the numerical aperture of the imaging equipment, the numerical aperture being the sine of the maximum refraction angle multiplied by the refractive index of the medium through which the light travels. The lenses in the highest resolution "dry" photolithography scanners focus light in a cone whose boundary is nearly parallel to the wafer surface. As it is impossible to increase resolution by further refraction, addit… WebNumerical aperture Lens development to improve resolution means increasing the numerical aperture (NA), a measure of how much light the lens system can collect and …
WebObjective lenses of higher numerical aperture are capable of producing smaller Airy discs, and therefore can distinguish finer detail in the specimen. The limit at which two Airy discs can be resolved into separate entities is often called the Rayleigh criterion.
