Resolving power of a diffraction grating

WebWhere, e + d = grating element n = order of spectrum Principle: It is based on the principle of Fraunhoffer diffraction through a diffraction grating. Theory: A diffraction grating has large no. of slits of equal width and separation. Let there are N parallel slits each of width e separated by opaque space d. So the grating element is (e + d).

WebThe angular separation between two objects must be. Θ = 1.22 λ D. Resolving power is defined as the inverse of the distance or angular separation between two objects which can be resolved through the optical instrument. Therefore, R e s o l v i n g P o w e r = 1 Δ Θ = d 1.22 λ. Thus, the higher the diameter d, the better the resolution. WebWhere: R = the resolving power of the grating (no unit); λ = the wavelength of incident light (m); Δλ = the smallest difference in wavelength that the grating can resolve (m); The resolving power is also equal to R = N × m.
