WebApr 7, 2024 · The Rayleigh criterion defines the resolution between two features. For an immersion lithography system, the wavelength is 193 nm, and the numerical aperture is 1.35, giving a minimum interspot distance of 87 nm. This distance might be reduced a little by the use of attenuated phase shifting masks; the improvement depends on the transmssion of ... WebJan 25, 2024 · Therefore, we need large apertures to improve the resolving power of a telescope. We can prove this using Rayleigh’s criterion. The resolving power for a telescope is inversely proportional to the angular separation between two distant objects. Rayleigh’s formula is generally used for evaluating the resolving power of the telescope.
