The two most important parameters in objective design are the numerical aperture (which determines the fine detail in the image) and the magnification, which decreases the area that is imaged. For ...

The measurement of the acceptance angle of an optical fiber, which is the maximum angle at which the core of the fiber will take in light that will be contained within the core. Taken from the ...

With a maximum numerical aperture (NA) of 0.2 ... more information can be gained efficiently from samples. The range of objectives with outstanding working distances offers versatility, while ...

The size of the Airy disk depends on the wavelength of the light (λ) and the numerical aperture (NA) of the objective lens. The spatial resolution of the microscope is determined by the ability to ...
