The 25 pages that link to Numerical aperture, each with the reason it gives.

• Fluorescence microscopyRelated: Objective numerical aperture affects both collected fluorescence and achievable spatial resolution.

• Optical fiberRelated: It describes the fiber’s light-acceptance cone and influences how light couples into its core.

• PhotolithographyRelated: Higher numerical aperture can resolve smaller printed features.

• MicroscopyRelated: Higher numerical aperture generally permits finer resolution and brighter images.

• Diffraction limitRelated: Higher numerical aperture admits larger angles and improves resolution.

• MagnificationCompared with: It affects detail and brightness, but increasing it does not itself increase magnification.

• MicroscopeRelated: It helps determine how much detail an optical microscope can resolve.

• Rayleigh criterionRelated: For microscopes, it determines the criterion’s resolution through aperture and refractive index.

• Optical resolutionRelated: Higher numerical aperture generally allows finer detail to be resolved.

• Confocal microscopyRelated: Objective numerical aperture strongly affects confocal resolution and light collection.

• Optical tweezersRelated: A high numerical aperture creates the steep intensity gradients needed for three-dimensional trapping.

• DVDRelated: The pickup optics’ numerical aperture helps resolve DVD’s tightly spaced marks.

• Airy diskRelated: It expresses the light-gathering geometry that controls diffraction-limited spot size.

• Paraxial approximationRelated: Large numerical aperture signals wide angular spread, often warning against paraxial models.

• Abbe diffraction limitRelated: It is one of the two quantities in the standard Abbe resolution relation.

• Compound microscopeRelated: It helps determine the objective’s light-gathering ability and resolving power.

• Fiber laserRelated: It helps describe how a fiber confines and collects guided light.

• Blu-rayRelated: Blu-ray’s high-aperture objective lens produces a smaller focused spot on the disc.

• Objective lensRelated: It governs the objective’s light-gathering power and achievable resolution.

• Aperture (optics)Related: It describes light-gathering ability in microscopes and other imaging systems.

• Optical microscopeRelated: A higher value lets the objective collect more light and distinguish finer details.

• Fresnel numberCompared with: It characterizes angular collection, unlike the Fresnel number’s distance-dependent diffraction scale.

• Diffraction-limited systemRelated: It expresses how strongly an imaging system can collect light and resolve fine detail.

• Optical fiber coreRelated: It quantifies the range of input angles that the core can guide.

• Timeline of microscope technologyRelated: It became a central design measure for the increasingly powerful objectives in this history.
