Effect of na on psf
WebWhen a lens with too low NA is used, the resulting collimated beam can be distorted (aberrated) or even truncated. There is a weak dependence of numerical aperture on the optical wavelength due to the wavelength … WebIt is known that the impact of the vectorial nature of electromagnetic fields is not negligible in such situations. A well-known effect that exemplifies the above is the asymmetry …
