Web2.1 Dispersion If light of diﬀerent wavelengths is deviated by a grating or prism through diﬀerent angles, θ, the rate of change of θ with wavelength, dθ/dλ is the angular dispersion. If the deviated light is brought to a focus by a camera of focal length, f, the linear dispersion, f dθ/dλ, measures the scale of the focussed spectrum.

Diffraction … WebDispersion is the ability of a grating to angularly separate adjacent wavelengths of light. The higher the separation, the higher the dispersion. Dispersion is strictly a function of …

WebJun 22, 2024 · Prisms and gratings are the two most common types of dispersive optics. The major difference between these two elements is that the dispersion of prisms is non-linear while gratings offer linear dispersion. The dispersion of prisms is efficient over a wide range of wavelengths and the throughput of a prism is usually pretty high (>90%).
