Description

The minimum distance of two separate points that are discernible.
Rayleigh resolution is given by the following formula:
0.61ｘλ/NA＝0.61ｘλ/ｎsinθ,
where λ denotes wavelength, NA numerical aperture, n refractive index, and θ the maximum angle formed by the light rays incident on the objective lens and the optical axis.
