WebDiffraction gratings are a key component of a monochromator, which is a device used to select a particular wavelength of light from a polychromatic light source. In a monochromator the diffraction grating is rotated to change the wavelength that aligns with and passes through the exit slit. WebUsually X-ray diffraction in spectrometers is achieved on crystals, but in Grating spectrometers, the X-rays emerging from a sample must pass a source-defining slit, then optical elements (mirrors and/or gratings) disperse them by diffraction according to their wavelength and, finally, a detector is placed at their focal points.
