Direction of diffraction orders from crossed diffraction gratings

Posted Posted in Academics, General

Diffraction gratings are common optical elements in spectrometers, fan-out gratings, dichroic mirrors, and other filter devices. One common aspect of all of these is that they split an incoming wave into multiple diffraction orders. The direction of the diffraction orders depends on the angle of incidence and period of the grating relative to the wavelength. […]
