WebThe resolution is the ability to separate wavelengths. It is usually expressed as the Full Width Half Maximum (FWHM). The resolution can be theoretically determined by multiplying the reciprocal dispersion of the grating by the slit width. The monochromator bandpass with a 1200 lines/mm grating is half that of the same arrangement with a 600 ... WebIn general, gratings have much greater dispersion than prisms. Resolving power of a grating: λ/ (Δλ) = mN. Here m is the order of the spot observed and N is the total number of slits in the grating illuminated by the light-source. An X-ray photon typically has a kinetic energy of about 1000 eV and a probability wavelength of about 10 -10 m ...

"WebJan 25, 2024 · The resolving power of a device depends on its resolution. The resolution of an optical instrument is defined as the shortest distance between two points on a specimen that can be distinguished by the observer’s eye or the camera’s lens installed in the optical device. In simple terms, it’s the least resolvable distance. " - Resolving power of a grating
