Grating interference
A holographic grating has sinusoidal grooves as the result of an optical sinusoidal interference pattern on the grating material during its fabrication, and may not be as efficient as ruled gratings, but are often preferred in monochromators because they produce less stray light. See more In optics, a diffraction grating is an optical component with a periodic structure that diffracts light into several beams travelling in different directions (i.e., different diffraction angles). The emerging coloration is a form of See more The wavelength dependence in the grating equation shows that the grating separates an incident polychromatic beam into its constituent … See more Diffraction gratings are often used in monochromators, spectrometers, lasers, wavelength division multiplexing devices, optical See more 1. ^ Srinivasarao, M.
