Ruled grating equation
Did you know?
The wavelength dependence in the grating equation shows that the grating separates an incident polychromatic beam into its constituent wavelength components at different angles, i.e., it is angular dispersive. Each wavelength of input beam spectrum is sent into a different direction, producing a rainbow of colors under white light illumination. This is visually similar to the operation of a Webb(1) known as the grating equation.The equation states that a diffraction grating with spacing will deflect light at discrete angles (), dependent upon the value λ, where is the …
Webbfringes in the plane of the grating, equivalent to the groove spacing on a ruled grating), is the angle of incidence, anda i b i is the angle of diffraction from the grating normal (the sign convention is such that means no diffraction; i.e.,b iip a zeroth order). Note that the grating equation can apply to angles WebbOptical gratings such as ruled or holographic gratings can be customized to the perfect size for your application.
