Resolution is a measure of how close two different spectral signals can be but still be differentiated as separate signals. For dispersive spectrometers, resolution is largely a function of slit width, W, and the reciprocal linear dispersion, Rd, of the monochromator.

Rayleigh's criterion for resolution

WebRayleigh criterion The Rayleigh criterion establishes a standard to characterize the Spatial Resolution of an optical device, that is: the minimum resolvable detail, or how much can two points be close to each other before they become indistinguishable due to the Diffraction limit.

The angular separation θ is then. θ = ( 1.22 λ ) / D. where λ is the wavelength of light, and D the aperture diameter.

WebThe Rayleigh criterion stated in the equation θ = 1.22 λ/D gives the smallest possible angle θ between point sources, or the best obtainable resolution.
